A is a fixed point at height H above a perfectly inelastic smooth horizontal plane. A light inextesnsible string of length L(>H) has one end attached to A and other to a heavy particle. The particle is held at the level of A with string just taut and released from rest. Find the height of the particle above the plane when it is next instaneously at rest .
