Question

If a body of moment of inertia 2 kg m 2 revolves about its own axis making 2 rotations per second, then its angular momentum (in J s ) is, 2 π, 4 π, 6 π, 8 π

MARKS App · Accepted Answer

Given, Moment of inertia of body I = 2 kg m 2 Rotation of the body in one second f = 2 We know that, Angular momentum L = I ω L = 2 × 2 π f L = 2 × 2 π 2 L = 8 π J s
