    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 respectively will be

    A)  - 0.5 m/s and 0.3 m/s

    B)  0.5 m/s and - 0.3 m/s

    C)  - 0.3 m/s and 0.5 m/s

    D)  0.3 m/s and 0.5 m/s

    Correct Answer: B

    Solution :

    They will exchange their velocity, so \[{{V}_{a}}=0.5m/s\,and\,{{V}_{a}}=-0.3m/s\]
