Question
A 1 kg object is located 1.5 m above the ground and 2.5 m below the ceiling. If the ground is chosen as the zero potential energy reference point, what is the gravitational potential energy of the object? If the ceiling is chosen as the zero potential energy reference point, what is the gravitational potential energy of the object? (Take g=10 m/s2)
Options
A
15J (relative to the ground) and 25J (relative to the ceiling)
B
15J (relative to the ground) and −25J (relative to the ceiling)
C
−15J (relative to the ground) and −25J (relative to the ceiling)
D
−15J (relative to the ground) and 25J (relative to the ceiling)
