पर्याय

• near its hinge

• in the middle of door

• at the far end of door

• none of these

Answer 1

A door is easy to open or close if the force is applied at the far end of door. 

Explanation:

The turning effect is greater when the force acts farther from the hinge. So, applying the force at the far end makes the door easier to open or close.
