Angular momentum

L

of body with mass moment of inertia

I

and angular velocity

\omega

rad / sec is equal to

View answer and explanation

Correct option: C

I\omega

Option C (

I\omega

) is correct because angular momentum is the product of moment of inertia and angular velocity.

Moment of inertia of a hollow cylinder of mass M and radius r about its own axis is Two particles of mass

{m_1}

{m_2}\,({m_1} > {m_2})

attract each other with a force inversely proportional to the square of the distance between them. If the particles are initially held at rest and then released, the centre of mass will The wheel of toy car rotates about axis. It slows down from 400 rps to 200 rps in 2s. Then its angular retardation in

\mathrm{rad}{\mathrm{s}^{ - 2}}

is When a ceiling fan is switched on, it makes 10 rotations in the first 4 s. How many rotations will it make in the next 4 s? (Assuming uniform angular acceleration) A particle of mass
