This post is all about how you can easily solve electric force and electric field problems. At a glance problems of physics can seem to be scary and overwhelming for some students but do not worry all you need to do is your willingness to solve problem. So first of all you need to read your problem carefully and then start using following protocol to solve your problems. The procedure I am going to write is for calculating electric forces but you can use the same procedure to calculate an electric field by simply replacing the charge of interest, q, with a convenient test charge and dividing by the test charge at the end. So, to calculate the force,
Today in this post I’ll be writing about the electricity and magnetism books that I feel might be good considering whiling studying this subject for your undergraduate exams and also for when you appear for entrance exams like JAM for getting admission in masters in physics from good university or institute
ELECTRICITY AND MAGNETISM by A Mahajan, A Rangwala :- This is the first book in my list and I really like this book as it is extensive in its content and things are explained pretty clearly. You can consider this book for its comprehensiveness. You can take a look at the preview of this book here
When you start preparing for competitive exams like PMT, IITJEE, AIEEEi am sure most of you face this question “From which book should I study Physics?”. There are lots of books available in the market in Physics for preparation of exams like IITJEE/AIEEE/PMT and it could be quite confusing choosing from numerous available options.I would advise you all to choose one good book for example NCERT book or concepts of physics by HC Verma for reading text and clearing your concepts in physics.
Almost all the examination carries these type of questions.So these questions are important for success for getting good ranks
Assertion – reason type question has these five different cases
1. Both assertion and reason are true, reason is correct explanation of assertion.
2. Both assertion and reason are true but reason is not a correct explain the assertion.
3. Assertion is true but reason is false.
4. Assertion is false but reason is true.
5. Both are false.
These type of questions test only the concepts of the students. A reasonably well-prepared student can answer these questions in a matter of a few seconds.
1) If the total external force acting on a rigid body is zero, then
(a) only linear momentum remains constant
(b) only angular momentum remains constant
(c) both linear momentum and angular momentum remains constant
(d) neither linear momentum nor angular momentum remain constant
2) A ball of mass M is tied to a string of length L is whirled round in a horizontal plane in a circle of radius R. The speed of the stone is increased beyond the maximum permissible value and the string breaks suddenly; then
(a) the stone will jerk radially outwards
1)What is the probability of getting 53 Thursday in a year ?
2)What is probability of getting 53 Mondays in a leap year ?
3)What is the probability that two people have same birthday ?
4)What is the probability that two people have different birthday ?
5)If a card is drawn from a well suffeled deck of 52 cards then what is the probability of getting a face card ?
6)If probability of happening of an event is 0.39. what wiil be probability of not
