Charges interaction

  1. Jul 23, 2015 #1
    what are the generalised and more quicker ways of finding Force that multiple charges (4 charges along the y-axis and x-axis at most) exert on the origin charge Q. i have used a cartesian plane to try solve for the vectors but seem to not get to the right answer.

    there's no "fast" way. you need to exploit all the symmetries you have, if you have no symmetry you just have to grind out the vector algebra and projections

    Using vector addition along x-axis and y-axis ?

    So what's your problem since you have got the way to solve it?
