Question

a tank contains mass 'm' of water to a height 'h' .what is its potential energy​

Answer 1

The potential energy (P.E) of water is equal to m.g.h

Explanation:

Mass of water = m

Height of water = h

As we know that:

• The potential energy of an object is due to its height.

• When an object is placed at a certain height it has certain amount of potential energy stored in it.
• The formula of potential energy (P.E)  = m.g.h

Therefore we can say that the potential energy of water at height "h is equal to m.g.h

i.e.

P.E = m.g.h
