When net torque is zero, the object can have zero angular acceleration and a constant angular velocity — not at rest.

If the torque on an object adds up to zero

A) the forces on it also add up to zero.

B) the object is at rest.

C) the object could be rotating and its center of mass could be accelerating linearly

D) the object could not be rotating and its center of mass could be accelerating linearly

E) None of the above.
