Torque is the result of a pair of forces acting to cause a turning effect. Torque is calculated as the product of force and distance. Which row gives the correct description of the force and the distance used to calculate the torque of a couple?

1. Athe magnitude of one force | the perpendicular distance between the two forces
2. Bthe sum of the magnitudes of both forces | the perpendicular distance between the two forces
3. Cthe magnitude of one force | the perpendicular distance from one force to the mid-point between the forces
4. Dthe resultant of the two forces | the perpendicular distance from one force to the mid-point between the forces
