A solid sphere of radius R and mass M is rolled by a force F acting at the top of the sphere as shown in the figure. The sphere starts from rest and rolls without slipping, then
Text Solution
Verified by ExpertsThe correct answer is:
A
work done by force F when the center moves a distance S is 2FS
When the centre moves a distance S, the topmost point displaces by 2S. The work done is by the force is
W= 2FS
