Point Charges Homework/Studying help

  1. Apr 6, 2005 #1
    Heres another similar question:

    Two point charges, q1= 0.50 x 10^-9 C and q2= 8.00 x 10^-9 C are seperayed by a distance of 1.20 m. At what point along the line joining the points charges, is the total electric field die to the two charges equal to zero?

    Can you find a distance r between the two charges where the magnitude of each field is equal?

    Hint: Since the charges are both positive the fields both repel.
