At what distance from a carbon nucleus is the electric potential 2.1 V?

    1. The problem statement, all variables and given/known data

    At what distance from a carbon nucleus is the electric potential 2.1 V? Carbon atoms have 6 electrons in the atomic shell.


    2. Relevant equations

    v= K Q / r^2 OR K Q / r (NOT SURE)

    3. The attempt at a solution

    use voltage potential for point charge

    Using either v= K Q / r^2 OR K Q / r (not sure)

    V given, Q ( 6* electron charge) , solve for r

    It's the forumula with "r" in the denominator. The "r^2" forumula is for the electric field.
