If a force (F ) is applied on a body and it moves with a velocity (v ), the power will be
Options
- A(F v )
- B( F V )
- C( F v^2 )
- D(F v^2 )
Correct answer
A. (F v )
Step-by-step solution
We know that, power is given as ( aligned & P= d W d t = d d t [F s] [ W=F s] & =F d s d t [For constant force F ] & P=F v [ v= d s d t ] aligned )
