In the figure shown, the two identical balls of mass M and radius R each, are placed in contact with each other on the frictionless horizontal surface. The third ball of mass M and radius `(R )/(2')` is coming down vertically and has a velocity `=upsilon_(0)` when it simultaneously hits the two balls and itself comes to rest. Then, each of the two bigger balls will move after collision with a speed equal to :

Options

A. `4v_(0)//sqrt5`
B. `2v_(0)//sqrt5`
C. `v_(0)//sqrt5`
D. none

Answer
