A solid sphere of radius R is rolled by ...

A solid sphere of radius R is rolled by a force F acting at the topo of the sphere as shown in the figure. There is no slipping and initially sphere is in the rest position, then (CM= centre of mass)

A

Work done by force F when the centre of mass move a distance S is 2 FS

B

speed of the CM when CM moves a distance S is `sqrt((20)/(7)(FS)/(M))`

C

work done by the Force F when CM move a distance S is FS

D

speed of the CM when CM moves a distance S is `sqrt((6)/(5)(FS)/(M))`
