A tank of size 5 m`xx` 5m `xx` 5m is full of water and built on ground. Find the potential energy of the water in the tank.

Text Solution

Verified by Experts

PE = mgh= `(V rho)gh` (as mass = volume xx density)
`=(125 xx 1000) (10) (5//2) J= 3125 xx 10^3 J`
[Volume of water `=5 m xx 5m xx5m = 125 m^3,` distance of CG of water in the tank from the ground = (5//2)m]
