हिन्दीTwo identical balls A and B having velocities of \( 0.5\text{ m/s} \) and \( -0.3\text{ m/s} \) respectively collide elastically in one dimension. The velocities of B and A after the collision respectively will be
Correct answer · Option 1
\( 0.3\text{ m/s} \) and \( 0.5\text{ m/s} \)
Explanation
For 1D elastic collision between two identical bodies, velocities are simply interchanged. Hence, velocity of A becomes \( -0.3\text{ m/s} \) and velocity of B becomes \( 0.5\text{ m/s} \).
