Homework Statement
What is the electric potential energy of the electron? The protons are fixed and cannot move, a=0.94 nm, s=1.24 nm.
Homework Equations
U=Vq=KQq/d
The Attempt at a Solution
U=Vq= 2KQq/d
K=8.99 x 10^9
Q=charge of proton 1.6 x 10^-19
q= charge of electron (-1.6)x10^-19
d= sqrt(a^2+s^2)
Also is my final anwser going to be negative? or should it be a positive?
