A solid sphere of radius R has moment of inertia / about its diameter. What will be moment of inertia of a shell of same mass and same radius about its diameter ?
Options
- A3 5 ।
- B5 3 ।
- C2 3 ।
- D2 5 ।
Correct answer
B. 5 3 ।
Step-by-step solution
For a solid sphere, I= 2 5 M R^2 For a spherical shell, aligned I^ & = 2 3 M R^2 & = 5 3 2 5 M R^2= 5 3 I aligned
