What is the quantity of work done when a crane lifts a 100-N block from 2 m above the ground to 6 m above
100 J
100 J
200 J
200 J
400 J
400 J
600 J
600 J the ground?
The quantity of work done is equal to the force applied multiplied by the distance over which the force is applied. In this case, the force applied is 100 N and the distance is 6 m - 2 m = 4 m.
Therefore, the quantity of work done is 100 N * 4 m = 400 J.
So the correct answer is 400 J.
