The electric potential energy of the charge is equal to the potential at the location of the charge, V, times the charge, q:
The potential is given by the magnitude of the electric field, E, times the distance, d:
So we have
(1)
However, the electric field is equal to the electrical force F divided by the charge q:
Therefore (1) becomes
And if we use the data of the problem, we can calculate the electrical potential energy of the charge:

Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is, kg
Height to which the object is raised above his head, m
Acceleration due to gravity is, m/s²
We know that for a mass raised to a height
, the change in potential energy is given as:
, where,
Now, plug in the given values and solve.
Therefore, the change in the potential energy is 700.7 J.
