Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Pseudo force is an apparent force that acts on all masses whose motion is described using a non-inertial frame of reference frame, such as rotating reference frame. Pseudo force comes in effect when the frame of reference has started acceleration compared to a non-accelerating frame. The force F does not arise from any physical interaction between two objects, but rather from the acceleration ‘a’ of the non-inertial reference frame itself. As a frame can accelerate in any arbitrary way, so can pseudo forces be as arbitrary (but only in direct response to the acceleration of the frame). For example, if you consider a person standing at a bus stop watching an accelerating car, he infers that a force is exerted on the car and it is accelerating. Here there is no problem and the pseudo force concept is not required But, if the person inside the accelerating car is looking at the person standing at the bus stop, he finds that the person is accelerating with respect to the car, though no force is acting on it. Here, the concept of pseudo force is required to convert the non-inertial frame of reference to an equivalent inertial frame of reference.
