A small mass m slides from a point A of smooth quarter circular surface of mass M (free to move) as shown in figure. Mass M lies on smooth ground. When m reaches point B of M : (AB is one-fourth part of a circle of radius ‘r’) [Line OA is horizontal and OB is vertical]
- velocity of m w.r.t. M is
- velocity of M w.r.t. ground is
- work done by normal reaction on m is zero
- none of these
The correct answer is: none of these
