Step-by-step explanation:

Work done is defined as dot product of force and displacement.

Let
denote work done.

Let
denote force.

Let
denote displacement.

So,
W=F.S

It is given that
F=25N

It is given that both of them are not moving.

So,
|s|=0

Since
$W=F.S=|F||S|cos(\text{angle between F and S})$

So,
W=0
