Homework Help: Electric field and potential

  1. Sep 12, 2009 #1
    1. The problem statement, all variables and given/known data
    If V = 0 at a point in space, must E = 0? If E = 0 at some point, must V = 0 at that point?

    2. Relevant equations

    3. The attempt at a solution
    V = 0 means there is no PE at that point is zero. However, the PE may have been converted to KE which would require a non-zero E field.

    Am I in the ballpark? Now, I just need the second part....

    What is the relation between E and V?
