Question

The angular velocity of a body moving with a constant speed v in a circle of radius is given by– (a) v2 /r, (b) vr, (c) v/r, (d) r/v​

Answer 1

Zero

Explanation:

In uniform circular motion ω constant so

a = dω / dt = 0

Answer 2

Answer:

Option C

Explanation:

When a body is moving with a constant speed v in a circle of radius r.

The angular velocity is given by

ω = $\frac{v}{r}$    . . . . . . . .(1)

being all constant, the angular acceleration is zero.

The correct option is C.
