A ball of mass m = 200 gm is suspended from a point A by an inextensible string of length L. Ball is drawn to a side and held at same level as A but at a distance root 3/2 L from A as shown. Now the ball is released. Then :( assume string applies only that much jerk which is required so that velocity along string becomes zero ).
