    Finding where net force is zero on q between two point charges

    Oh wow.. thanks! That makes so much more sense than what my TA taught me! Totally made my day! Thank you so much! :D

    Finding where net force is zero on q between two point charges

    The answer is 1.9m. I still don't understand it because since both the charges are positive, wouldn't the forces be in the other direction (no forces in between both the charges) since they are going to repel each other?

    Finding where net force is zero on q between two point charges

    Homework Statement Two point charges, 3q and q lie along x-axes. 3q is at 0.00 m and q is at 3.0m. Find the point between the 2 charges at which the net force on charge q is zero. Homework Equations F=kq1q2/r^2 The Attempt at a Solution Really can't figure this one out. Missed the...
