Answer:

Row D ; 280 Nm

Explanation:

Workdone is the product of the force applied and the distance moved. This means :

Workdone = Force * distance

For each of rows A to D:

Row A :

Workdone = 20 N * 20m = 400 Nm

Row B :

Workdone = 40 N * 10m = 400 Nm

Row C :

Workdone = 50 N * 6m = 300 Nm

Row D :

Workdone = 70 N *4m = 280 Nm

From the result obtained above, the smallest amount of workdone on the trolley is given in Row D ; which is 280Nm
