(b)

For pure rolling,

Solving the above equations, we get,

So the object may be a ring or a hollow cylinder

Next Question :

A solid sphere rests on a horizontal surface. A horizontal impulse is applied at height  from centre. The sphere starts starts rolling just after the application of impulse. The ratio will be

 a) b) c) d)
