JEE MainPhysicsRotational MotionMCQ+4 / −1
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 T1T2{{{T_1}} \over {{T_2}}}T2​T1​​ will be :
  1. A
    23{{\sqrt 2 } \over 3}32​​
  2. B
    23{2 \over {\sqrt 3 }}3​2​
  3. C
    23{2 \over 3}32​
  4. D
    32{3 \over {\sqrt 2 }}2​3​
