Two workers, Amit and Sumit, need to load identical heavy wooden boxes into a truck bed. Amit uses a $3\text{ m}$ long ramp, while Sumit uses a $5\text{ m}$ long ramp to reach the same height. Which statement correctly describes their effort?
Amit applies less force because his ramp is shorter.
Sumit applies less force because his ramp has a gentler slope.
Both workers apply the exact same force because the truck height is identical.
Sumit does zero work because the ramp is longer.
Solution
A longer inclined plane reaching the same height has a smaller slope angle, requiring less effort force spread over a longer distance.
