```

W = F * d

```

Where:

- W represents the work done (in joules)

- F represents the force applied (in newtons)

- d represents the displacement (in meters)

If the force is increased by 5 times, the work done will also increase by 5 times, assuming that the displacement remains constant. This is because work is directly proportional to the force applied.

For example, if a force of 10 newtons is applied to move an object a distance of 5 meters, the work done would be:

```

W = 10 N * 5 m = 50 J

```

If the force is increased to 50 newtons, the work done would become:

```

W = 50 N * 5 m = 250 J

```

Therefore, we can see that the work done increases by 5 times when the force is increased by 5 times.
