A solid sphere of mass m and radius R is connected with a wire of length L cross section area A, young's modulus Y, and torsional constant C .If sphere is slightly pulled downward and released then time period of motion is `T_(1)` and if sphere is rotated a small angle in the horizontal plane about an axis passing through the thread and released then time period of motion is `T_(2)` .Then `(T_(1))/(T_(2))` is `(1)/(R)sqrt((nCL)/(YA))` then value of `2n` is (R<
