1. The problem statement, all variables and given/known data Find the electric field (both magnitude and direction) at point P located between the charges q1 = -3C and q2 = +4C. Point P is 1/3 of the charges' separation distance from q1 and 2/3 of the charges' separation distance from q2. 2. Relevant equations E = kq/d^2 Etotal = E1 + E2 3. The attempt at a solution I am able to infer that the direction of the electric field points to the left of P. I also know that, due to the above equations, Etotal = (9E9 * 3)/(2/3x)^2 + (9E9 * 4)/(2/3x)^2 therefore Etotal = 3.24E11/x^2 However, I am having trouble finding the distance between the charges q1 and q2. Is there a point between q1 and q2 where the electric field is zero that I can set kq1/d^2 equal to kq2/d^2? I would appreciate any help finding the distance between the two given point charges.
