Two equal balls are in contact on a table and are in equillibrium. A third ball collides with them simultaneously, symetrically and remains at rest after the impact. The coefficient of restitution is :

A)2/3

B)3/2

C)1/3

D)1/2

2. Relevant equations

3. The attempt at a solution

i hav tried by combining the masses and velocities of the two balls at rest then found e. like the collision of two bodies ( considering two bodies as one ) .
