Question

A body of mass $M$ is moving with a uniform speed of $10 blank m divided by s$ on friction less surface under the influence of two forces $F subscript 1 end subscript$ and $F subscript 2 end subscript$ . The net power of the system is

$10 F_{1} F_{2} M$
$10 (F_{1} + F_{2}) M$
$(F_{1} + F_{2}) M$
Zero

The correct answer is: Zero

$because$ Speed is constant
$therefore$ Work done by forces = 0
$therefore$ Power $equals fraction numerator W o r k over denominator T i m e end fraction equals 0$
