A body of mass 2kg collides with a wall with speed 100 m/s and rebounds with same speed. If the time of contact was 1/50 second, the force exerted on the wall is

`8N`

`10^4 N`

`2 xx 10^4 N`

Text Solution

Verified by Experts

The correct Answer is:

`F xx t `= change in momentum or F ` = 400 xx 50 N = 2 xx 10^4 N`
