Coulomb Law

  1. Dec 2, 2013 #1
    1. The problem statement, all variables and given/known data


    Three charges are in a straight row. The first charge has a value of 5.00 x 10-5 C. The second charge also has a value of 5.00 x 10-5 C and is 2.50 cm to the right of the first charge. The third charge has a value of -2.50 x 10-5 C and is 2.00 cm to the right of the second charge.
    Find the net charge in the first, second and third charge
    2. Relevant equations

    F=kq1q2/r^2

    3. The attempt at a solution

    Just wanted to check if I'm doing this right.
    For the first charge, I got -30444N , the second ; -7875N and the 3rd; 33681N.

    Thanks

    I take it you meant net force.

    Show your work for at least one charge, and we can tell you if your method is correct.
