Question

door 1 had its knob on the opposite side of the door as the hinges and door 2 has its door knob close to the hinge side of the door . suppose both doors require he same amount of torque to open. Which door would require you to push for a greater distance to open it?

Answer 1

Step-by-step explanation:

Torque is defined as the product of force applied and the perpendicular distance.

Torque = force x distance

It is a vector quantity and its SI unit is Nm .

According to the question, the torque is same in both the cases. So, the distance of knob 2 is less than the distance of knob 1, so we have to apply more force on knob 2 to open the door.
