To solve the problem of what happens to the moment of inertia (M.I.) about a vertical axis through the center when a metal ring is melted and formed into a solid sphere, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Moment of Inertia**: The moment of inertia (I) is a measure of an object's resistance to changes in its rotation. It depends on the mass distribution relative to the axis of rotation. 2. **Moment of Inertia of a Metal Ring**: ...

A non - conducting ring of mass m = 4 kg and radius R = 10 cm has charge Q = 2 C uniformly distributed over its circumference. The ring is placed on a rough horizontal surface such that the plane of the ring is parallel to the surface. A vertical magnetic field B=4t^(3)T is switched on at t = 0. At t = 5 s ring starts to rotate about the vertical axis through the centre. The coefficient of friction between the ring and the surface is found to be (k)/(24) . Then the value of k is
