A person pulling a wall does no work because the wall does not show any displacement. Because work done = force x displacement.
Sibce displacement is 0 therefore work done is equal to zero.

Hey mate!Here is your answer:-
A person is pulling the wall, we think that he has done/is doing work but actually he has done/is doing zero work because Work is defined as the product of Force and Displacement.
Work is directly proportional to the Force as well as Displacement.
The person is applying the Force but there is no Displacement with respect to time. So,pulling a wall is not considered as work.
Hope it helps you.....
