A) The ball will roll out of the glass bowl near edge 'Q'.
B) It will stop at centre point 'R' after a number of to-and-fro motions.
C) It will keep moving between point 'P' and 'Q' and will never stop.
D) It will not move at all since friction is required for movement.
Correct Answer: C
Solution :
In the absence of friction (no opposing motion), a moving object will keep on moving. In this case, the ball will oscillate between points'?' and 'Q' due to the action of gravitational force.You need to login to perform this action.
