Q.
A body of mass M is moving with a uniform speed of 10 m/s on frictionless surface under the influence of two forces $F_{1}\ $and $F_{2}$. The net power of the system is
A) $10\ F_{1}F_{2}M$
B) $10(F_{1} + F_{2})M$
C) $(F_{1} + F_{2})/M$
D) Zero
Explanation
(d) As the speed of mass is uniform hence, net power will be zero.
