High-yield problems without answer again ;[
"Three positive charges, +1e, +2e, +3e, are sitting in a row with 5mm between them. What is the Potential Energy of the system?"
Is the Potential Energy simply the sum of the potential between all the charges?
U12=q1k(q2/r12)
U13=q1k(q3/r13)
U23=q2(q3/r23)
Utotal= U12+U13+U23
