1. The problem statement, all variables and given/known data (a) What is the electric potential energy in joules of two electrons separated by 2.43 nm? (b) What would be it be if the separation was doubled? 2. Relevant equations i think v=kq/r 3. The attempt at a solution (a) 1.185 J (b) 0.95 J i cant figure out what im doing wrong, im following the book example.
