Two equal forces are applied perpendicular to a door. The first force is applied

Question

Two equal forces are applied perpendicular to a door. The first force is applied at the midpoint of the door; the second force is applied at the doorknob. Which force exerts the greater torque?

Two equal forces are applied perpendicular to a door. The first force is applied at the midpoint of the door; the second force is applied at the doorknob. Which force exerts the greater torque?

1-The force applied at the midpoint of the door exerts the greater torque. 2-The force applied at the doorknob exerts the greater torque. 3-Both forces exert equal nonzero torques. 4-Both forces exert zero torques.

Explanation / Answer

Here ,

as the torque due to two forces is given as

Torque = force * distance from axis

for the force at the midpoint , distance is smaller than the force at the door knob

the force with greater torque is

2-The force applied at the doorknob exerts the greater torque.
