The moment of inertia of a circular disc about an axis passing through its centre and perpendicular to the plane is `4 kg m^(2)` . Its moment of inertia about the diameter is

Options

A. `2kg m^(2)`
B. `6 kg m^(2)`
C. `4kg m^(2)`
D. `8 kg m^(2)`

Answer

A

Explanation

`I_(d)=(I_(c ))/(2)=(4)/(2)=2 kg m^(2)`
