The S-shaped unifrom wire shown in figure has a mass M, and the radius of curvature of each half is R. The moment of inertia about an axis through A and perpendicular to the plane of the paper is:

A

`3/4 MR^(2)`

B

`MR^(2)`

C

`3/2 MR^(2)`

D

`2MR^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
In the plane Required `I=I_(1)+I_(2)`
`therefore I_(1)=(MR^(2))/(2) and I_(2)=(MR^(2))/(2)+MR^(2)`
`therefore I=2MR^(2)`
