Hello,

Potential energy is the energy that is stored in an object due to its position relative to some zero position. The potential energy is equal to the mass*height*acceleration due to gravity which is MGH.

So if the mass is 10 Kilo gram and the height is 20 meters with assuming acceleration due to gravity as 10 meter/second. The potential energy is 10*20*10 which is equal to 2000J.

Dear aspirant hope you are doing well.

We know the formula of potential energy is mass multiple acceleration due to gravity multiple hight

E= m*g*h= 10*10*20= 2000 joules.

E - potential energy

m - mass - 10kg

g - acceleration due to gravity. - 10 m/s^2

h - height - 10metres
