The torque because it is a cross product must be perpendicular to both the force applied and the radius of the particle. The scoring guidelines typically show numerical results using the value. From experience, we know that the same force will be much more effective at rotating an object such as a nut or a door if our hand is not too close. They have even linked to my own video solutions to these problems. We should have the long answer graded and posted by wednesday and exams will be returned.
