Question

In uniform circular motion

• A. Both the angular velocity and the angular momentum vary
• B. The angular velocity varies but the angular momentum remains constant
• C. Both the angular velocity and the angular momentum stay constant
• D. The angular momentum varies but the angular velocity remains constant

Answer 1

Answer: (C)

. Both the angular velocity and the angular momentum stay constant

The angular momentum is given by,

$L=I\omega$.

We know that, in uniform circular motion $\omega =constant$

$\therefore L=constant$.
