Statement 1: |
It is harder to open and shut the door if we apply force near the hinge |

(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 |
