Consider 3 identical balls, each having mass of 0.1 kg. The ball A has an initial velocity of `10 sqrt( 3) m//s`. It then collides simultaneously with balls B and C, whose centres are on a line perpendicular to the initial velocity of the ball A. They are initially in contact with each other and are at rest. The ball A is aimed directly at the contact point of B and C. After the collision, if the ball A comes to rest, then

Options

A. Collision in elastic.
B. Collision is inelastic and final kinetic energy of the system-Initial kinetic energy of the system = 5J
C. Collision is inelastic and final kinetic energy of the system - Initial kinetic energy of the system = - 5J
D. Collision in elastic, but the final kinetic energy of the system is less than the initial kinetic energy of the system.

Answer

C
