Expert Solution
Step 1

Given data

The charge on both the proton is, q1=q2=+e

The distance between the charges is, d.

 

The electric potential energy is proportional to the product of charges and inversely proportional to the separation between the charges.

And the proportionality constant for this is ke also known as the coulombs constant.
