Which of the following has the greatest amount of gravitational potential energy (gravity = 9.8 m/s²)?

• A 20 kg projector suspended 10 m in the air

• A 100 kg wrecking ball suspended 10 m in the air

• A 5 kg basketball suspended 10 m in the air

• They all have the same GPE because they are all 10 m in the air
