    Understanding the Components of Electric Charge Equation

    Homework Statement The question lies in the equation, I do not understand where the SQRT of 3Q or the 2L^2 is coming from? Can somebody help me with this? The professor kinda breezed by this but I cannot find a valid explanation anywhere! Thanks in advance!

    Calculating Charge Magnitude for Nickel Coin Using Coulomb's Law

    Well, I know that C=6.02 x 10^18 electrons, and I have 1.245 x 10^24 electrons, also the problem states that there are 28 electrons/atom on the nickel coin... would I multiply those?
