A) \[3M{{R}^{2}}\]
B) \[\frac{4}{5}M{{R}^{2}}\]
C) \[\frac{2}{3}M{{R}^{2}}\]
D) \[M{{R}^{2}}\]
Correct Answer: A
Solution :
\[I={{I}_{1}}+{{I}_{2}}+{{I}_{3}}={{I}_{1}}+2\times {{I}_{2}}\] \[(\because {{I}_{2}}={{I}_{3}})\] \[=\frac{1}{2}M{{R}^{2}}+2\times (M{{R}^{2}}+\frac{M{{R}^{2}}}{4})=3M{{R}^{2}}\]You need to login to perform this action.
