The picture below shows three elevators, each carrying a different number of people to different floors. If all the people weigh the same, which elevator is doing the most work? (Weight = Force, and Number of floors = Amount of displacement)

Select one:
a. Elevator 1 is doing the most work.
b. Elevator 2 is doing the most work.
c. Elevator 3 is doing the most work.
d. They're all doing the same amount of work.

Option D

They are all doing the same amount of work

Explanation:

For Elevator 1

For Elevator 2

For Elevator 3

Here,

W = F • d

For Elevator 1

W = 1 • 10

W = 10 Nm

For Elevator 2

W = 2 • 5

W = 10 Nm

For Elevator 3

W = 10 • 1

W = 10 Nm

Here, In each case the work done is same.

Thus, They're all doing the same amount of wwork
