Properties of Electric Charge Some fundamental properties of the electric charge are as follows: Quantization - This property of electric charge suggests that the total charge of a body can represent the integral multiple of a basic quantum of charge. Additive - This property of electric charge suggests that the total charge of a body can represent the total sum of all the singular charges that seem to be acting on the system. Conservation - This property of electric charge suggests that the total or the whole charge of a particular system remains unaffected with time. In simple words, when an object gets charged due to some friction, a transfer of charge from one object to another object occurs. A charge is a thing which can't be destroyed or created. Electric Field An electric field is considered as the electric force that is present in one unit of charge. The direction of the field is considered to be the same as the direction of the force, and it is expected to exert on a positive test charge.

When the electric field is radially outward, then it is considered as a positive charge, and when the electric field is radially inward, then it is considered as a negative charge. The SI unit of the electric field is volt per meter. In simple words, we can define the electric field as a physical field which can be found surrounding each electric charge and is responsible for exerting force on all the other charges present on the field. Electric fields are believed to be originated from electric or from time-varying magnetic fields.

Guide To The AP Physics 1 Exam
Both electric fields and magnetic fields are considered as the manifestations of the electromagnetic force, which is one of the four fundamental forces that exist in nature or the environment. Properties of Electric Field The following are considered as the properties of an electric field: The lines that are present in the electric field never intersect with each other. The lines in the electric field are perpendicular to the surface charge. When the lines are closely held together, the field is strong, but when the lines are loose and are not close together, the field is weak. The number of lines in the field is directly proportional to the magnitude of the charge. The lines in the electric field seem to start from a positive charge and end with a negative charge.

Multi-select questions require two of the listed answer choices to be selected to answer the question correctly. AP Physics 1 Free Response Questions The free response section consists of five multi-part questions, which require you to write out your solutions, showing your work. Unlike the multiple-choice section, which is scored by a computer, the free-response section is graded by high school and college teachers. They have guidelines for awarding partial credit, so you may still receive partial points should you not correctly respond to every part of the question. Can you use a calculator on the AP Physics exam? You are allowed to use a calculator on the entire AP Physics 1 Exam—including both the multiple-choice and free-response sections.

Explain this beautiful aphorism on the nature and practice of science. Answer: Science is a systematised study of observations. A scientist patiently analyses these observations and comes out with certain laws. As an illustration, Tycho Brahe worked for twenty long years to make observations on planetary motions. It is from this huge reservoir of observations that Kepler formulated his three famous laws of planetary motion. Thus, science is the art of the soluble just as politics is the art of the possible. Question 1. Though India now has a large base in science and technology, which is fast expanding, it is still a long way from realising its potential of becoming a world leader in science.

Physics: Answers To End-of-Chapter Questions & Exam Style Questions.
Name some important factors, which in your view have hindered the advancement of science in India. Answer:Some of the important factors which have hindered the growth of science in India are given below: Lock of infrastructure and funds for quality research work in science. Science education is neither properly oriented nor directed. It needs specific directions depending on our requirements. The rural based science education is nearly non-existent so that majority of population is deprived of the benefits of advancements in science and technology. Poor pay scales and other facilities to scientists as compared to administrators. Indian society is full of superstitions and is highly traditional. Therefore, they are slow in adopting the new scientific trends. There is practically no co-ordination between the researchers and the industrialists. The industrialists are the actual consumers of new research and technology.

The shells of crabs found around a particular coastal location in Japan seem mostly to resemble the legendary face of a Samurai. Given below are two explanations of this observed fact. Which of these strikes you as a scientific explanation? As a tribute to his bravery, nature through its inscrutable ways immortalised his face by imprinting it on the crab shells in that area. Consequently, the particular shape of the crab shell survived longer and therefore in course of time the shape was genetically propagated. This is an example of evolution by artificial selection.

Two persons sitting on the globe or on moon would talk on phone face to face. Man may partially conquer diseases and slow down ageing. How, if at all, will you resolve your dilemma? Answer: A scientist aims at truth. A scientific discovery reveals a truth of nature. So, any discovery, good or bad for mankind, must be made public. A discovery which appears dangerous today may become useful to the mankind some time later. In order to prevent misuse of scientific technology, we must build up a strong public opinion. Scientists should in fact take up two roles — to discover truth and to prevent its misuse. Science, like any knowledge, can be put to good or bad use, depending on the user. Given below are some of the applications of science.

The technique helps to remove certain type of deformations in needy persons. But plastic surgery for cosmetic purposes is not good. India has had a long and unbroken tradition of great scholarship in mathematics, astronomy, linguistics, logic and ethics. Yet, in parallel with this, several superstitious and obscurantistic attitudes and practices flourished in our society and unfortunately continue even today among many educated people too. How will you use your knowledge of science to develop strategies to counter these attitudes? Answer: In order to popularise scientific explanations of everyday phenomena, mass media like radio, television and newspapers should be used.

We shall use our knowledge of science to educate masses and shall try to tell them the real cause of an event so that their superstitious beliefs are rejected. Demolish this view using scientific arguments, and by quoting examples of great women in science and other spheres; and persuade yourself and others that, given equal opportunity, women are on par with men. Answer: There is no difference in the capacity of women and men as far as work, intelligence, decision making is concerned.

The nature makes little difference in man and woman in their anatomy and feeling. The nutrition content of prenatal and postnatal diet contributes a lot towards the development of human mind. If equal opportunities are afforded to both men and women, then the female mind will be as efficient as male mind. The list of successful women from various fields is very large. Dirac held this view. Criticize this statement. Look out for some equations and results in this book which strike you as beautiful. Answer: Generally it is considered that physics is a dry subject and its main aim is to give qualitative and quantitative treatment i. It is felt that truth of an equation is more important than the simplicity, wonderfulness, symmetry or beauty of the equation.
