Physics · Rotational Mechanics
According to Routh's rule, the moment of inertia for a spherical body about any axis passing through its center of gravity is given by: (where M = Mass of the body and S = Sum of the squares of two semi-axes)
- 1I = M × S 2
- 2I = M × S 4
- 3I = M × S 5✓
- 4I = M × S 3
Correct answer
I = M × S 5
