The force ‘F’ acting on a particle o f mass ‘m ’ is indicated by the force-time graph shown below.
The change in momentum of the particle over the time interval from zero to 8 s is

A

24 ns

B

20 ns

C

12 ns

D

6 ns

Text Solution

Verified by Experts

The correct Answer is:
C
Change in momentum of the particle over the time interval from 0 to B second is
Area of `Delta p = (Delta OAB - (##KPK_AIO_PHY_XI_P1_C05_E05_047_S01##) BCDE + (##KPK_AIO_PHY_XI_P1_C05_E05_047_S02##) FGHE)`
`=(1)/(2) xx 2 xx 6 -2 xx 3 xx 4`
`=6-6 + 12`
`=12 Ns`
