Two identical concentric rings each of mass m and radius R are placed perpendicularly. What is the moment of inertia of the system about the axis of one of the rings ?

Options

A. `3/2 MR ^(2)`
B. `2 MR ^(2)`
C. `MR ^(2)`
D. `1/4 MR ^(2)`

Explanation

As the axis of two rings are also perpendicular to other,
`therefore,` using theorem of perendiclar axis ,
`I = MR ^(2) + (1)/(2) MR ^(2) = (3)/(2) MR ^(2)`
