The force ‘F acting on a particle of 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 :
Answer & explanation
Correct answer: option 3
Change in momentum, \(\Delta p = \text{Area of F-t graph} \)
=\(\frac{1}{2}\)×2×6 -3×2 + 4×3
= 12Ns
