A box of mass m slides down a frictionless inclined plane of length L and vertical height h. what is the change in its gravitational potential energy?

A

`-mgL`

B

`-mgh`

C

`-mgL//h`

D

`-mgh//L`

Text Solution

Verified by Experts

The correct Answer is:
B
Since the box (mass m) falls through a vertical distance of h, its gravitational potential energy decreases by mgh. The length of the ramp is irrelevant here.
