    Where Should a -3 MicroCoulomb Charge Be Placed to Achieve Zero Net Force?

    Thankyou. The force of the 3mC charge from the other two chargers were about .02 difference. Basically one was 9.7*10^(-11) and the other was 9.9*10^(-11). Close to zero as possible, but thankyou.

    Where Should a -3 MicroCoulomb Charge Be Placed to Achieve Zero Net Force?

    I subsituted b for 80-a so using the equation you gave q1= 4mC q2=8mC 4mC*[(80-a)^2] = 8mC*[a^2] = 4mC* (6400-160a+[a^2]) = 8mC*a^2 which seems more confusing then just doing problem itself

    Homework Statement Two charges are separated as shown. Where would you place a -3 microCoulombs (mC) charge such that the net force on this charge is 0? + + 4mC 8mC Distance between charges are 80cm apart...
