A solid sphere of radius

R

is placed on a smooth horizontal surface. A horizontal force '

F

' is applied at height '

h

' from the lowest point. For the maximum acceleration of the centre of mass, which is correct?

View answer and explanation

Correct option: D

No relation between

h

and

R

Option D is correct because the acceleration of the center of mass depends only on the applied force and the mass of the sphere, not on the height at which the force is applied since the surface is smooth.
