What is Equilibrium
A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion
The general conditions for equilibrium are as follows
(i) The total force must be zero
(ii) The total torque about any axis must be zero.
In many cases it is convenient to consider torques about axes through the centre of gravity.
Types of equilibrium
We can divide the equilibrium into two categories With respect to the state of a body
1. Static equilibrium.
2. Dynamic equilibrium.

With the advent of robotics, there is a lot of high… Read More »
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.
