A particle of mass m moving with velocity u makes an elastic one-dimentional collision with a stationary particle of mass `m`. They come in contact for a very small time `t_0`. Their force of interaction increases from zero to `F_0` linearly in time `0.5t_0`, and decreases linearly to zero in further time `0.5t_0` as shown in figure. The magnitude of `F_0` is

A

`(m u)/(T)`

B

`(2m u)/(T)`

C

`(m u)/(2T)`

D

`(3m u)/(2T)`

Text Solution

Verified by Experts

The correct Answer is:
