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. `MR ^(2)`
C. `2/5MR ^(2)`
D. `3/2 MR ^(2)`

Explanation

Moment of inertia of a uniform circular disc about an axis through its centre and peropendicular to its plance is
`I _(C) = (1)/(2) MR ^(2)`
By the theorem of parllel axes,
`I = I _(C) + Mh ^(2) =(1)/(2) MR ^(2) + MR ^(2) =(3)/(2) MR ^(2)`
Moment of inertia of a uniform circular disc about an axis touching the disc at its diameter and normal to the disc is` 3/2 MR ^(2)`
