Question

if the body is at rest or rotating with uniform angular velocity the angular acceleration will be zero in this case the torque acting on a body will be zero and why​

Answer 1

Answer:

because it is in rest position

Answer 2

Answer:

torque acting on a body will be zero.

Explanation:

in this case angular acceleration is zero,

so torque will be

τ= I×α [ 2nd law for rotational motion]

τ= I(0)

τ= 0
