Question

A ring is hung on a nail. It can oscillate, without slipping or sliding
(i) in its plane with a time period T₁ and,
(ii) back and forth in a direction perpendicular to its plane,
with a period T₂. The ratio ${{{T_1}} \over {{T_2}}}$ will be :

${{\sqrt 2 } \over 3}$

${2 \over {\sqrt 3 }}$

${2 \over 3}$

${3 \over {\sqrt 2 }}$
