A man in a lift feels an apparent weight W when the lift is moving up with a uniform acceleration of 1/3rd of the acceleration due to gravity. If the same man were in the same lift now moving down with a uniform acceleration that is 1/2 of the acceleration due to gravity, then his apparent weight is

A block of mass 'm' is placed on the floor of a lift, moving upward with an uniform acceleration a = g. ( mu is the coefficient of friction between block and the floor of lift). If a horizontal force of umg acts on the block, then horizontal acceleration of the body is .......
