The balancing point between two point charges

  1. Aug 20, 2013 #1
    Where is the potential zero?

    1. Where is the potential zero between a negative (-.03c) and a positive charge (.27) separated by 1 meter?

    2. Point charges laws

    3. My text book doesn't mention where is potential zero between two charges, it's easy to solve if i know the point is in between or outside and which point charge is it closer to, kq/d=kq/d

    [tex]\frac{k\cdot 0,27}{d}+\frac{k\cdot (-0,03)}{D}=0[/tex]

    two different d.

    And you need another equation...
