If a force F is applied on a body and it move with velocity v, then power will be :- |
|
Answer» Power = Work/ Time. Work = Force x displacement So, now Power = Force x displacement / Time. But displacement / Time = velocity According to the question, Force is F and V is velocity so, Power = F x v But power is a scalar quantity so, we have dot product for power so...... Power = Fv or F.v option 1 is the answer |
