# Problem: What is the electrostatic potential energy (in joules) between two protons that are separated by 63 pm?

###### FREE Expert Solution

In this problem, we are asked to determine the electrostatic potential energy (in joules) between two protons that are separated by 63 pm.

Recall electric force is the force that pushes apart two like charges, or that pulls together two unlike charges. It can be calculated using the following equation:

$\overline{){{\mathbf{U}}}_{{\mathbf{E}}}{\mathbf{=}}\frac{{\mathbf{kq}}_{\mathbf{1}}{\mathbf{q}}_{\mathbf{2}}}{\mathbf{r}}}$

where: UE= electricostatic potential energy;
q1 and q2 = charges;
k = Coulombs constant = 8.99x109 J•m/C2;
r = distance of separation
