M R²
M R²/2
3 M R²/2
2 M R²/5

Question 967

▼

How is the moment of inertia of a composite body calculated?

By averaging
By multiplying
By adding moments of inertia of parts about same axis
By vector addition

Question 968

▼

What is the role of the axis in determining moment of inertia?

It has no role
It only matters if external torque is present
It defines the reference for mass distribution
It changes the mass

Question 969

▼

Can two different bodies have the same moment of inertia?

No, never
Only if same material
Yes, if mass and distribution are adjusted
Only in vacuum

Question 970

▼

It doubles
It quadruples
It halves
No change
