Question

discuss the motion of two bodies with different mass connected at the end of light inextensible string which goes over frictionless and massless pulley

Answer 1

Answer:

In reality, pulleys are not massless. When a pulley is rotating, there has to be an unbalanced torque in the direction of rotation. ... Coming back to the question, in general, when the pulley is at rest or rotating at a constant velocity then there is no unbalanced force and tension on both sides can be assumed same.
