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
