Two identical balls A and B having velocities of 0.5 m/s and `-0.3` m/s respectively collide elastically in one dimension. The velocities of B and A after the collision repsectively will be `……….`

A

`-0.3 m//s , 0.5 m//s `

B

`0.3 m//s ,0.5 m//s `

C

`-0.5 m//s ,0.3 m//s `

D

`0.5 m//s , -0.3 m//s `

Text Solution

Verified by Experts

The correct Answer is:
A
Since both balls are identical and collision is elastic so velocity will interchange .
So `v_(B) = 0.5 , v_(A) = - 0.3 `
