Question

A solid sphere of radius $R$ is placed on smooth horizontal surface. A horizontal force $F$ is applied at height $h$ from the lowest point. For the maximum acceleration of centre of mass

• A. $h=R$
• B. $h=2R$
• C. $h=0$
• D. The acceleration will be same whatever h maybe

Answer 1

The correct option is D The acceleration will be same whatever h maybe

The linear acceleration of centre of mass will be $a=\frac{F}{m}$ where the force is applied. Hence acceleration will be same whatever the value of $H$ may be.
