Question

What is the amount of work done by a man pressing a rigid wall with a force of 200 N?

Answer 1

Step 1: Given data

Force applied, $F=200N$

Since the man does not move, it can be said that displacement is $S=0$.

Step 2: Calculating work done

Work done is given by,

$W=FS$

where, $F$ is force and $S$ is displacement.

Substituting the known values, we get,

$\begin{array}{l}W=200N\times 0\\ W=0Joule\end{array}$

The amount of work done by a man pressing a rigid wall with a force of 200 N will be zero, as there is no net displacement.
