an electron and a proton are initially very far apart. They are thenbrjought together to form a hydrogen atom, in which the electron orbits the proton at an average distance of 5.29x10^-11 m. What is the change in electric potential energy?

Explanation:

Given that,

The distance between the electron and proton,

We need to find the change in electric potential energy. It can be calculated as follows :

Where

k is the electrostatic constant

Change,

Put all the values.

So, the required change in electric potential energy is .
