A vessel containing 50 kg of water is placed at a height 15 m above the ground. Assuming the gravitational potential energy at ground to be zero, what will be the gravitational potential energy of water in the vessel? (g = 10 m s-2)

Mass of water, m = 50kg

Height, h = 15m

Gravitational potential energy = mgh

= 50 × 10 × 15

= 7500 J
