A solid sphere has mass ' M ' and radius ' R '. Its moment of inertia about a parallel axis passing through a point at a distance R 2 from its centre is

Options

A8 MR ^2 11
B11 MR ^2 18
C7 MR ^2 10
D13 MR ^2 20

Correct answer

D. 13 MR ^2 20

Step-by-step solution

Concept: Parallel axis theorem application. The moment of inertia for a sphere about the central rotation axis is: I _ sphere = 2 5 MR ^2 See the diagram below, To find the moment of inertia about the new rotation axis we use parallel axis theorem:
