    Potential Due to a Collection Charges

    Right, initially I thought there was no field because I calculated it to equal zero. Then I realized that the potential is relative and can have whatever value. This material is best understood if you graph the potentials for the two cases.

    Potential Due to a Collection Charges

    Ok, I think I figured it out. See if you can follow my logic. First of all, the potential is whatever you define it to be because you can add a constant. For the proton in the middle of two other protons, its potential is the same as a proton the same distance away from a particle of...

    Potential Due to a Collection Charges

    My text reads for Potential Due to a Collection Charges: 1/(4πє) ∑ q/r I'm consfused about the distance and how it's treated as a scalar. Let's say you want to calculated the potential between two protons. If a proton (or electron) is placed in the middle, there will be no net force...
