A sphere of mass `5kg` and diameter `2 m` rotates about a tangent. What is its moment of inertia in `kg m^(2)` ?

Text Solution

Verified by Experts

The correct Answer is:
`(7)`
Here,`m = 5 kg, r = (2)/(2) = 1m , I = ?`
Moment of inertia of the sphere about a tangent
to the sphere, `I = (7)/(5)mr^(2) = (7)/(5)xx 5 xx 1^(2) = 7 kg m^(2)`
