PYQ NEET- Rotational Motion L-8

Question: 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#

A) $h=R$

B) $h=2 R$

C) $h=0$

D) the acceleration will be same whatever $h$ may be

Answer: the acceleration will be same whatever $h$ may be#

Solution:#

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