A non-uniform ball of spherically symmetric mass distribution, radius 'R' and radius of gyration about geometric centre = R/2, is kept on a frictionless. The geometric centre coincides with the centre of mass. The ball is struck horizontally with a sharp impulse = J The point of application of the impulse is at a height 'h' above the surface. Then :

A non-uniform ball of spherically symmetric mass distribution, radius

1.	A non-uniform ball of spherically symmetric mass distribution, radius 'R' and radius of gyration about geometric centre = R/2, is kept on a frictionless. The geometric centre coincides with the centre of mass. The ball is struck horizontally with a sharp impulse = J The point of application of the impulse is at a height 'h' above the surface. Then :
Answer» the ball will slip on surface for all cases the ball will roll purely if H = 5R/4 the ball will roll purely if h = 3R/2 there will be no ROTATION if h = R Answer :B::D
