Static Electricity

  1. Feb 5, 2012 #1
    1. The problem statement, all variables and given/known data
    Two points charges A(+10. uC) and b(+40.0 uC) are placed .2 m apart forming line ab. Calculate the force experienced by a point charge C(+10.0 uC) placed on line Ab, .06 m from A

    2. Relevant equations
    F=kq1q2/d^2

    3. The attempt at a solution
    First I tried making a diagram of this problem but it didnt really help me in anyway because all I could get out of it was the angle measures. I tried using F=kq1q2/d^2 and plugged in .06 as the distance and 10 uC as the charge but then what would be the point of knowing the two other charges so I think I'm doing something wrong. Can someone tell me what 2 do please

    Hi,

    What do you mean you found angle measures? If they're all on a straight line, there shouldn't be any angles.

    Are you aware of the principle of superposition of forces?
