Question

A tank of radius 14 m and height 10 m full of water and built on ground . Find potential energy of water in the tank . ​

Answer 1

Explanation:

volume of tank = 10 × 10 × 10=> 1000m³

we know that:-

mass = density × Volume => 10³m³ × 1000kg/m³ => 106 kg

now, P.E = mgh

[ here height = 5m from the mid point of tank]

PE = 106× 10 × 5

=> 5 × 107joule

hope it helps you✔✔

Answer 2

$\huge{\underline{\mathtt{\red{☆A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R☆}}}}$

volume of tank = 10 x 10 x 10=> 1000m3

we know that:

mass = density x Volume => 10°m3 X

1000kg/m => 106 kg

now, P.E = mgh

[ here height = 5m from the mid point of

tank]

PE = 106x 1O × 5

=> 5 x 107joule
