## Homework Statement

At the point of fission, a nucleus of 235U with 92 protons is divided into two smaller spheres, each with 46 protons and a radius of 5.9x10^-15m. What is the repulsive force pushing these two spheres apart?

## Homework Equations

F = k(qi)(q2)/d^2

## The Attempt at a Solution

I'm not quite sure what to use for the numerator of the equation. I believe that 5.9x10^-15m would be used as the distance. So, part of the equation would be (9*10^9)(x)(x)/5.9x10^-15.

Can anyone lead me to what numbers I SHOULD be using or at least give me a hint? Thank you! :)
