A particle of mass $\displaystyle M$ is moving in a circle of fixed radius $\displaystyle R$ in such a way that its centripetal acceleration at time $\displaystyle t$ is given by $\displaystyle n^2 R t^2$ where $\displaystyle n$ is a constant. The power delivered to the particle by the force acting on it, is :
Official answer
(1)
$\displaystyle M n^2 R^2 t$
