<h2>Explanation:</h2>

In physics, work is defined force that causes displacement. So this can be expressed by the following equation:

W=Fs

Where:

F:Force \\ \\ s:Displacement

The force can be found as:

F=ma \\ \\ F=5(10)=50N

And for the displacement:

s=6-2=4m

The force (weight) is down and the displacement is up, then the work must be negative. So:

W=-(50)(4) \\ \\ \boxed{W=-200J}
