Find the SI unit of moment of inertia. 5.64 kg mass of a object is moving uniformly. The radius of gyration is measured as 30 cm of an object. Then what is the moment of Inertia?

Text Solution

Verified by Experts

Mass `=5.64` kg
radius of gyration `=30cm=0.3m`
SI unit of a mass is kg
SI unit of the radius (gyration) `=m^(2)=0.9`
Moment of inertia (I)`=` mass `xx` radius of gyration
`=5.64` kg `xx` 0.9m=1.5228kgm^(2)`
