Answer :
- The potential energy of the body is 50 joule.
Given :
- Gravity = 10 m s¯¹
- Mass = 1 kg
- Height = 5 m
To find :
- The potential energy of the body =?
Step-by-step explanation :
We know that, the potential energy of a body is calculated by using the formula :
Potential energy = m x g x h
In this case, mass, m = 1 kg
Acceleration due to gravity,
g = 10 m s¯²
and, height, h=5 m
So, putting these values in the above formula, we get
Potential energy = 1 x 10 x 5
= 50 J
Thus, the potential energy of the body is 50 joule.

According to the Question
❍ Given:-
⋄ Acceleration due to gravity (g) = 10m/s²
⋄ Mass of the body (m) = 1kg
⋄ Height of the body ( h) = 5m
❍ To Find:-
⋄ Potential energy of the body (P. E)
❍ Solution :-
➧Potential Energy = mgh
➧P. E.= 1×10×5
➧ P. E=50Joule.
∴The Potential Energy of the body is 50J.

✰Extra Knowledge :-
➧ The energy of an object because of its position or shape is called its potential energy.
➧ P. E. =mgh
where
m is the mass of object
g is the acceleration due to gravity
h is the height of object
