The moment of inertia of a uniform circular disc of radius R and mass M about an axis passing from the edge of the disc and normal to the disc is:
Options
- AM R^2
- B1 2 M R^2
- C3 2 M R^2
- D7 2 M R^2
Correct answer
C. 3 2 M R^2
Step-by-step solution
M.I. of disc about its normal = 1 2 M R^2 M.I. about its one edge =M R^2+ M R^2 2 M.I. = 3 2 M R^2
