Ler l be the moment of inertia of a uniform square plate about an axis AB that passes through its centre and is parallel to two of its sides. CD is a line in the plane of the plate that passes through the centre of the plate and makes an angle `theta` with AB. The moment of inertia of the plate about the axis CD is then equal to

Options

A. `I`
B. `I sin^(2) theta`
C. `Icos^(2) theta`
D. `Icos^(2)`

Answer

A

Explanation

`I_(AB)=1/6 ml^(2)=I_(CB)` (irrespective an angle)
