A solid uniform cylinder of mass M and radius R is pivoted at its centre free to rotate about horizontal axis. A massless inextensible string is wrapped around it, and attached to a block of mass m which is initially at a height h above the floor. The acceleration due to gravity is g, directed downward. The block is released from rest. By what total angle does it rotate ` Delta theta ` (in radians)

A

` sqrt(1+(2M)/(m))`

B

`(h)/(R)`

C

`sqrt(1+(h)/(2R))`

D

`(MR)/(mh)`
