A 2.40 kg ball is attached to a ceiling by a 2.00 m long string. The height of the room is 3 m. What is the gravitational potential energy of the ball relative to:

a) the ceiling?

b) the floor?

c) a point at the same elevation as the ball?

Variables

P for potential energy

m for mass in kg

g for gravity

h for height

2. Relevant equations

P=mgh

3. The attempt at a solution

For b), I found the answer which was 23.52.

For a), though, I got 70.56 because P=(2.4)(9.8)(3)=70.56. The 3 is from the fact that the ceiling is 3m off the ground and a) is asking about the ceiling. It says that I'm wrong

For c), I don't have any idea of what they're talking about. Is it the same thing as b)?
