A `100g` iron ball having velocity `10m//s` collies with a wall at an angle `30^(@)` and rebounds with the same angle. If the period of contact between the ball and wall is `0.1` second, then the force experinced by the wall is

A

10 N

B

100 N

C

1 N

D

0.1 N

Text Solution

Verified by Experts

The correct Answer is:
A
`F=(2m u sin theta )/(t) `
`f=(2xx0.1xx10xx(1)/(2))/(0.1)=10N`
