A cloud of thickness 10 m and area `10^(6)m^(2)` is formed at a height of 2 km above the ground. If the density of water is `10^(3)kgm^(-3)`, then calculate the potential energy of the cloud `(g=9.8ms^(-2))`.

Text Solution

Verified by Experts

Given `d=10m,A=10^(6)m^(2),h=2xx10^(3)m,rho=10^(3)kgm^(-3)`
i.e. `m=rhoAd=10^(3)xx10^(6)xx10=10^(10)kg`
i.e. `P.E.=mghxx10^(10)xx9.8xx2xx10^(3)`
P.E. = `1.96xx10^(14)J`
