If the torque on an object adds up to zero

the forces on it also add up to zero.
the object could be accelerating linearly but it could not be turning.
the object cannot be turning.
the object is at rest.
the object could be both turning and accelerating linearly.

Respuesta :

Answer: If the torque on an object adds up to zero  then the object could be both turning and accelerating linearly.

The net  torque on object is zero connotes that the object will not have angular acceleration but  will have angular velocity. Therefore the object will rotate.  Also the center of mass of the object will have linear acceleration because  there will be net force.

Therefore, the correct option is the object could be both turning and accelerating linearly.
