What is the power given by centripetal force?(in circular motion)
The power given to the particle by the
force acting on it is?
MY ATTEMPT:
Since force and velocity are radial power must be zero, but the answer is not zero . … If I find instantaneous power then I am getting $P_i = 2 \pi m k^2 r^2 t$.
Where $P_i$ = instantaneous power,
The answer given is option (b), as in the following figure, but why? …
