The force $‘F\text{'}$ acting on a particle of mass $‘m\text{'}$ is indicated by the force-time graph shown below. The change in momentum of the particle over the time interval from zero to $8 \mathrm{s}$ is:

• A

  $24 \mathrm{N}\mathrm{s}$
• B

  $20 \mathrm{N}\mathrm{s}$
• Correct answer
  C

  $12 \mathrm{N}\mathrm{s}$
• D

  $6 \mathrm{N}\mathrm{s}$

Hence, the correct answer is option: 'C'.
