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

A. `(1)/(2) MR^(2)`
B. `(7)/(2)MR^(2)`
C. `(3)/(2)MR^(2)`
D. `MR^(2)`

Answer

C

Explanation

`I=I_(cm)+ Md^(2)=(MR^(2))/(2)+MR^(2)=(3)/(2) MR^(2)`
