In the figure given below, the position-time graph of a particle of mass `0.1kg` is shown. The impuslse at `t=2` sec is

A

`0.2 kg m//s`

B

`-0.2 kg m//s`

C

`0.1 kg m//s`

D

`-0.4 kg m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
Between `t = 0` and `t = 2 s` ,
`v =` slope of x -t graph `= (4)/(2) = 2 m//s`
`t gt 2 s , v = 0`
`Delta p = p_(2) - p_(1) = 0 - mv = 0 - 0.1 xx 2 = -0.2 kg m//s`
