Laws of Motion

A lift is moving down with acceleration \(a.\) A man in the lift drops a ball inside the lift. The acceleration of the ball as observed by the man in the lift and a man standing stationary on the ground are respectively

A light string passing over a smooth light pulley connects two blocks of masses \({m_1}\) and \({m_2}\) (vertically). If the acceleration of the system is \(g/8\), then the ratio of the masses is

Three identical blocks of masses \(m=2\) \(kg\) are drawn by a force \(F=10.2\) \(N\) with an acceleration of \(0.6\) \(m{s^{ - 2}}\) on a frictionless surface, then what is the tension (in \(N\)) in the string between the blocks \(B\) and ...
