A particle is moving with a uniform speed in a circular orbit of radius R in a central force inversely proportional to the $\displaystyle \mathrm{n}^{\text {th }}$ power of R. If the period of rotation of the particle is T, then :
Official answer
(3)
$\displaystyle \mathrm{T} \propto \mathrm{R}^{(\mathrm{n}+1) / 2}$
