Two balls marked 1 and 2 of the same mass m and a third ball marked 3 of mass M are arranged over a smooth horizontal surface as shown in the figure. Ball 1 moves with a velocity `v_(1)` towards ball 2. All collisions are assumed to be elastic. If `Mltm`, the number of collisions between the balls will be.

Text Solution

Verified by Experts

The correct Answer is:
B
After collision between 2 `&` 3 moves, 2 moves forward so only 2 collision.
