A) \[\text{10 M}{{\text{R}}^{2}}\]
B) \[\frac{37}{9}\text{ M}{{\text{R}}^{2}}\]
C) \[\text{4 M}{{\text{R}}^{2}}\]
D) \[\frac{40}{9}\text{ M}{{\text{R}}^{2}}\]
Correct Answer: C
Solution :
\[M=\frac{9M}{\pi {{R}^{2}}}\times \frac{\pi {{R}^{2}}}{9}=M\] \[I=\frac{(9M){{R}^{2}}}{2}-\left[ \frac{M{{\left( \frac{R}{3} \right)}^{2}}}{2}+M{{\left( \frac{2R}{3} \right)}^{2}} \right]\] \[I=4M{{R}^{2}}\]You need to login to perform this action.
