What work will be done by a man who pushes a wall ?

We know, work done $W=F\times d$

Where $F\rightarrow$ Force acted on a body

$d\rightarrow$ displacement produced in the body

When a man pushes a wall, there is no displacement$( d=0)$.

Then the work done $W=F\times (0)=0$

Thus, when a man pushes a wall the work done is zero.
