Question:medium

A solid sphere of radius \(10\) cm is rotating about an axis which is at a distance \(15\) cm from its centre. The radius of gyration about this axis is \( \sqrt{n} \) cm. Find the value of \( n \).

Show Hint

Radius of gyration directly reflects how mass is distributed about the axis—parallel axis theorem is essential here.
