Question

the potential energy of a bucket of water of mass 20 kg will be ------------- if the mass of bucket is increased by 22kg

Answer 1

Answer:

the the way of getting to grips did not have one or is that the only way you

Answer 2

• Here h & g = constant in both the cases

• Heavier mass = 20 kg

• Relatively lighter mass = 10 kg

• ∵ PE = mgh,

• ∴ PE′ (heavier mass) = 20gh

• And, PE″ (lighter mass) = 10gh

• Since, 20gh > 10 gh ⇒ PE′ > PE″.

• Therefore, the potential energy of a bucket of water of mass 20 kg on the first floor of the house is MORE than the potential energy of bucket of water of mass 10 kg on the same floor.
