Question

A body is moving with a constant speed v in a
circle of radius r. Its angular acceleration is
(a) vr (b) v/r
(c) zero (d) vr²

Answer 1

Answer:

When a body is moving with a constant speed v in a circle of radius r. being all constant, the angular acceleration is zero.

Answer 2

Answer:

Zero.

Explanation:

As velocity is constant angular velocity is also constant.

w= v/r

here w is angular velocity.

v is velocity that is constant.

r is radius that is constant.

all terms are constant hence a=0

As angular velocity is constant angular acceleration is 0.

Hope this answer is helpful.
