A man standing in a lift falling under gravity releases a ball from his hand. As seen by him the ball

A person of mass m is standing in a lift. Find his apparent weight when the lift is (iii) Falling freely (g is the acceleration due to gravity).

A small steel ball of mass m and radius r is falling under gravity through a viscous liquid of coefficient of viscosity eta . If g is the value of acceleration due to gravity. Then the terminal velocity of the ball is proportional to (ignore buoyancy)
