A) 1 : 2
B) \[\sqrt{3}:\sqrt{5}\]
C) \[\sqrt{5}:\sqrt{3}\]
D) 5 : 4
Correct Answer: C
Solution :
For solid sphere, moment of inertia \[{{I}_{1}}=\frac{2}{5}M{{R}_{1}}^{2}\] For hollow sphere \[{{I}_{2}}=\frac{2}{3}M{{R}_{2}}^{2}\] Taking, \[{{I}_{1}}={{I}_{2}}\] \[\frac{{{R}_{1}}}{{{R}_{2}}}=\sqrt{\frac{5}{3}}=\sqrt{5}:\sqrt{3}\]
