Coulombs Law and Electric Charges

  1. Jan 16, 2005 #1
    Likewise, this similar problem also has me stumped
    A charge of 7.00 mC is placed at each corner of a square 0.80 m on a side. Determine the magnitude of the force on each charge.

    Any help would be greatly appreciated!

    OMG,this is funny... :rofl: :rofl: :rofl: :rofl: :rofl:

    Do you know what an equilateral triangle is???

    I'm insulted.

    Yes, I know what an equilateral triangle is. It has three sides of equal length, and all three angles are 60 degrees. As I stated, I found the net force on two of the points, but Q(1) is giving me issues. Obviously the way I'm trying is wrong, so I'd like help, thank you.

    You deleted the problem.Anyway,since you know what a equilateral triangle is,u might use the fact that the problem is symmetric (actually the geometry) so the directions of the forces are equivalent.If the charges were all 3 equal,then the problem would b solved if u managed to find the net foce acting only on one angle,since on the other two is practically the same,in modulus,of course.
