Question

A wall, acted upon by a force of 20 N,
does not move. The work done in this
process is​

Answer 1

Answer:

The work done is ZERO because

Work done = force*displacement of the object

As displacement of wall = 0m

Work done = 0J

Answer 2

Answer:

The wall acted upon a 20 N will not move because the wall again exerts a force 20 N to the body which is exerting force and it is a balanced force, in balanced force there is no acceleration.

Therefore the work done it this process is zero.
