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 \(\left(F_1+F_2\right) v\)
- D Zero
Answer & Solution
Correct Answer
(D) Zero
Step-by-step Solution
Detailed explanation
\(F_{net} = Ma = M(0) = 0\) \(P_{net} = F_{net}v = (0)v = 0\)
