Passage : When a solid object is suspended from a point and allowed to oscillate such that the distance between point
P
of suspension and its centre of mass is \( \mathrm{d} \), its moment of inertia about point of suspension is I and its mass is
W
If that object is disc and suspended about the tangential point such that axis is perpendicular to the plane of disc, then its time period is
(1) \( 2 \pi \sqrt{\frac{3 R}{2 g}} \)
(2) \( 2 \pi \sqrt{\frac{R}{g}} \)
(3) \( 2 \pi \sqrt{\frac{3 R}{g}} \)
(4) \( 2 \pi \sqrt{\frac{R}{2 g}} \)
