Why is it easier to open a door by applying a force on the door knob as compared to say a point in the Centre of the door?

Answer:It’s simple. You apply same force in each case but torque is different. Torque acting on the hinge is more if the point of force applied is farther from hinge. And larger is the perpendicular distance from the axis of rotation, less is the force needed to move it.

Why a force is applied at right angles to the heavy door?

To create torque we have to apply force normal to axis of rotation,so we apply force at right angles to close or open a door. When we apply a force to the heavy door at its outer edge then perpendicular distance increases, so we have to exert less force on door. This force creates torque and door starts rotating.
