1.

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
