A particle moving in a circle of radius $\displaystyle R$ with a uniform speed takes a time T to complete one revolution.
If this particle were projected with the same speed at an angle ' $\displaystyle \theta$ ' to the horizontal, the maximum height attained by it equals 4R. The angle of projection, $\displaystyle \theta$, is then given by :

From NTA’s final answer key for this paper.
(4)
$\displaystyle \theta=\sin ^{-1}\left(\frac{2 \mathrm{gT}^2}{\pi^2 \mathrm{R}}\right)^{1 / 2}$
