why it is easier to open a door by holding it from its edges?

Answer 1

Answer:

It is easier to open a door by holding it from its edge as the displacement from the edge to the hinge of the door is the maximum, which gives a larger moment of force with a small force applied by us, hence, the door opens with lesser effort as compared to the case when we open the door by holding it from anywhere .
