Question

A particle is revolving in a circular path of radius 2m with constant angular speed 4 rad/s. The angular acceleration of particle is

Answer 1

Answer:

The angular acceleration of the particle is zero

Explanation:

Given

The radius of the circular path r = 2 m

Angular velocity ω = 4 rad/s

Angular acceleration α is rate of change of angular velocity

$\boxed{\alpha=\frac{\omega}{t}}$

Therefore,

Here in the question, the angular velocity is given as constant

Therefore, the angular velocity is not changing with time

Thus, angular acceleration α = 0

Hope it helps.

Answer 2

Answer:

ZERO

Explanation:

Given

The radius of the circular path r = 2 m

Angular velocity ω = 4 rad/s

Angular acceleration α is rate of change of angular velocity

Therefore,

Here in the question, the angular velocity is given as constant

Therefore, the angular velocity is not changing with time

Thus, angular acceleration α = 0
