Assuming that they have not made any mistakes in their calculations what might account for the difference? A. The dot product of the torque vector and the force vector is zero. B. Torque is always a matter of opinion. C. One student views the torque from the left while the other views the torque from the right. D. Torque is measured about a specific point and the students have chosen different points.
