A ring is hung on a nail. It can oscillate, without slipping or sliding (i) in its plane with a time period $\displaystyle \mathrm{T}_1$ and, (ii) back and forth in a direction perpendicular to its plane, with a period $\displaystyle \mathrm{T}_2$. The ratio $\displaystyle \frac{\mathrm{T}_1}{\mathrm{~T}_2}$ will be :
Official answer
(3)
$\displaystyle \frac{2}{\sqrt{3}}$
