Let us hang a small block of mass m is fixed at the upper end of a mass less vertical spring of spring constant K = 2mg/l and natural length 21L. The lower end of spring is free and is at a height L form fixed horizontal floor. The spring is initially unstressed and the spring-block system is released from rest.As the instant speed of the block is maximum, the magnitude of force exerted by the spring on the block is1. 42 mg2. mg3. zero4. None of these
