The correct answer is
(B) For a solid cylinder, the maximum possible value of $a$ is $2 \mu g$
(D) For a thin-walled hollow cylinder, $a=\frac{F}{2 m}$
Rotational motion can be defined as the motion of an object around a circular path, in a fixed orbit.
The wheel or rotor of a motor, which appears in rotation motion problems, is a common example of the rotational motion of a rigid body.
