A ring is suspended from a point S on its rim as shown in the figure. When slightly displaced from equilibrium, it oscillates in its plane with a time period of 1 second. The radius of the ring is (take $g = π^{2}$ ):-

Options:

Answer:

Solution:

Physical pendulum about rim point S: $I = 2 m R^{2}$ , $d = R$ .

$T = 2 π \frac{2 R}{g}$ with $T = 1$ , $g = π^{2}$ .

$1 = 2 2 R \Rightarrow R = \frac{1}{8} m = 12.5 cm$
