A body is in rotational motion. Is it necessary that a torque be acting on it ?

A body is set into rotational motion due to

A rigid body is rotating. Is it necessary that a net torque acts on the body is zero ?

A rigid body is rotating about a vertical axis at n rotations per minute, If the axis slowly becomes horizontal in t seconds and the body keeps on rotating at n rotations per minute then the torque acting on the body will be, if the moment of inertia of the body about axis of rotation is I.

A body is rotating in steady rate. What is torque acting on the body?

Rotational Motion - Torque

A body is rotating on a steady rate. Is a torque acting on the body? Why?

Rigid Body|Rotational Motion

If the resultant torque of all the forces acting on a body is zero about a point is it necessary that it will be zero about any other point?

If the resultant torque of all the forces acting on a body is zero about a point is it necessary that it will be zero about any other point?
