Moment of inertia of a uniform circular ...

Moment of inertia of a uniform circular disc about a diameter is `I`. Its moment of inertia about an axis perpendicular to its plane and passing through a point on its rim will be.

A

5I

B

6I

C

3I

D

4I

Text Solution

Verified by Experts

The correct Answer is:
B
Given, `I= (MR^(2))/(4) rArr MR^(2)= 4I`
Required MOI `= (MR^(2))/(2) + MR^(2)= (3)/(2) MR^(2)`
`rArr (3)/(2) (4I)= 6I`
