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.
