A slight horizontal force is exerted by a rod on a ball with a radius of 20 cm. Determine the value of H for which the ball rolls without slipping on ground. (Assume that there is no friction between ground and ball during the impact.) 15.0 cm 32.0 cm 45.0 cm 28.0 cm 50.0 cm

Solution

Solution:

For ball to be rolling without slipping, neccessary condition is that tangent velocity component at point touching the ground should be zero.

or we can say angular acceleration acting on body should be equal to angular acceleration times radius

but here neither F magnitude is not given nor angular speed, please check for complete information. (some data is missing)

Option c & e can\'t be correct answer beause then force will be acting outside ball.
