A body of mass ' $M$ ' is moving with a uniform speed of ' $v$ ' on a frictionless horizontal surface under the influence of two forces $F_1$ and $F_2$ as shown in the figure. The net power of the system is

• A

  $\left(\mathrm{F}_1-\mathrm{F}_2\right) \mathrm{v}$
• B

  $0.5\left(\mathrm{~F}_1+\mathrm{F}_2\right) \mathrm{v}$
• C

  $\left(F_1+F_2\right) v$
• Correct answer
  D

  Zero

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