Moment of inertia of a rigid body about an axis through its centre of gravity is `10kg m^(2)` . If mass of the body about an axis parallel to the first axis and separated by a distance of 1m is

Options

A. `12 kg m^(2)`
B. `8 kg m^(2)`
C. `4 kg m^(2)`
D. `2 kg m^(2)`

Answer

A

Explanation

`I_(0)=I_(c )+Mh^(2)`
`= 10+2xx1=12 kgm^(2)`.
