A molecule of mass m moving with a velocity v makes 5 elastic collisions with a wall of the container per second. The change in its momentum per second will be

5 mv

`(mv)/10`

10 mv

Text Solution

Verified by Experts

The correct Answer is:

Change in momentum in one collision
= mv - (-mv) = 2mv
`therefore` For 5 collisions, the change in momentum/sec = 10 mv
