A is a fixed point at height H above a perfectly inelastic smooth horizontal plane. A light inextesnsible string of length `L(gtH)` 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 .
A. velocity of particle on the surface is `=sqrt(2gh) cos theta`
B. velocity of particle when it leaves surface `=sqrt(2gh) cos^(2) theta`
C. `S=(h^(5))/(l^(4))`
D. None of these
