A ball A collides elasticlly with an another identical bass B with velocity 10 m//s at an angle of `30^(@)` from the line joining their centres `C_(1)` and `C_(2)` Select the correct alternative (s).

A

Velocity of ball P after collision is 4 m/s

B

Velocity of ball Q after collision is `5sqrt(3)` m/s

C

both the ball move at right angle after collision

D

kinetic energy will not be conserved since collision is not a head - on - collision.
