Answer Key / Explanation : (c) -

(c)

Torque = Force  perpendicular distance of line of action of force from the axis of rotation (d)

Hence for a given applied force, torque or true tendency of rotation will be high for large value of . If distance  is smaller, then greater force is required to cause the same torque, hence it is harder to open or shut down the door by applying a force near the hinge
