a tank of size 10m×10m×10m is full of water and built on the ground.if g=10m/s^2,the potential energy of water in the tank is? |
|
Answer» => 1000m³ we know that:- mass = density × Volume => 10³m³ × 1000kg/m³ => 10^6kg now, P.E = mgh [ here HEIGHT = 5m from the mid POINT of tank] p.e = 10^6 × 10 × 5 => 5 × 10^7 joule
