विकल्प

• `"I"_0/8`

• `"I"_0/4`

• 8I₀

• 2I₀

Answer 1

The moment of inertia of a circular disc of mass M and radius R about an axis passing through the centre of mass is I₀. The moment of inertia of another circular disc of same mass and thickness but half the density about the same axis is 2I₀.
