1.	A solid sphere of radius R is rolled by a force F acting at the topo of the sphere asshown in the figure. There is no slipping and initially sphere is in the rest position, then (CM= centre of mass)
Answer» Work DONE by force F when the CENTRE of mass move a distance S is 2 FS speed of the CM when CM moves a distance S is `sqrt((20)/(7)(FS)/(M))` work done by the Force F when CM move a distance S is FS speed of the CM when CM moves a distance S is `sqrt((6)/(5)(FS)/(M))` ANSWER :A::B
