Correct Answer - Option 3 : Kg.sq metre
Explanation:
Moment of Inertia:
The moment of inertia plays the same role in rotational motion as mass plays in linear motion. It is the property of a body due to which it opposes any change in its state of rest or of uniform rotation.
And the moment of inertia of a particle is given as
\({\rm{I = m}}{{\rm{R}}^{\rm{2}}}\)
where, m = Mass of the particle, R = Distance from the axis of rotation.
Unit: kg.m2
