In figure a block of mass m is released from rest when spring was in its natural length The pulley also has mass m but friction less Suppose the value of m is such that finally it is just able to lift the block M up after releasing it www M Rod String A The weight of m required to just lift M is Mg 2 Mg B The tension in the rod when m has an acceleration is zero 2 C The normal force acting on M when m has zero acceleration is UP
