A) \[5kg-{{m}^{2}}\]
B) \[2.7kg-{{m}^{2}}\]
C) \[3.5kg-{{m}^{2}}\]
D) \[4.5\text{ }kg-{{m}^{2}}\]
E) \[4kg-{{m}^{2}}\]
Correct Answer: C
Solution :
Moment of inertia of sphere about tangent \[I=\frac{2}{5}M{{R}^{2}}+M{{R}^{2}}=\frac{7}{5}M{{R}^{2}}\] \[=\frac{7}{5}\times 10\times {{(0.5)}^{2}}=3.5\,kg-{{m}^{2}}\]
