Homework Statement
Three electrons form an equilateral triangle 0.800 nm on each side. A proton is at the center of the triangle.
Homework Equations
U = k[(q_1*q_2)/r]
The Attempt at a Solution
I tried to use the following equation:
k*[(3e^2)/(0.8*10^-9) - (3e^2)/(0.4*10^-9)]
I plugged in 1.602*10^-19 for both e-values, and got the following answer:
-6.4*10^-19 Volts
However, it says that "I do not have the correct dimensions." I'm not sure what that error means or what I did wrong, so any help would be appreciated.
