Question
Assertion :It is harder to open and shut a door if we apply force near the hinge Reason: Torque is maximum if force is applied at the hinge of the door
Assertion :It is harder to open and shut a door if we apply force near the hinge Reason: Torque is maximum if force is applied at the hinge of the door
Open in App
Solution
The correct option is C Assertion is correct but Reason is incorrect
As the torque is the product of force and perpendicular distance from the pivot. So we need a maximum torque for easy opening or shutting a door by applying minimum force. But the force is maximum and torque is minimum near the hinge.Thus, assertion is correct and reason is incorrect.
