If the sum of the external torques on an object is zero, then the sum of the external forces on it must also be zero. C. If the sum of the external forces on an object is zero, then the sum of the external torques on it must also be zero. D. If an object remains at rest, then the sum of both the external torques and the external forces on the object must be zero. E. If the sum of both the external torques and the external forces on an object is zero, then the object must be at rest.
