Electric Field Problem -Easy plz help 1. The problem statement, all variables and given/known data Two point charges, q1 = 4.0×10-6 C and q2 = -1.0×10-6 C, are located on the x axis at x1 = -1.0 cm and x2 = 3.0 cm. Determine the x coordinate of a point on the positive x axis where the electric field is zero; i.e., a test charge placed at this point would experience no force. 2. Relevant equations kq/(r^2) 3. The attempt at a solution Don't know, please help, I would like to know how to solve this.
