A particle of mass m is moving with speed u. It is stopped by a force F in distance x if the stopping force is 4 F then

A

work done by stopping force in second case will be same as that in first case.

B

work done by stopping force in second case will be 2 times of that in first case.

C

work done by stopping force in second case will be `(1)/(2)` of that in first case.

D

work done by stopping force in second case will be `(1)/(4)` of that in first case.

Text Solution

Verified by Experts

The correct Answer is:
A
As `triangleKE` is same in both the cases, work done will be same.
