    Calculating the Current in a Two battery Combination Circuit

    Nope! Those two equations were all I needed. It turns out I had mixed up the numbers for R2 and R3. :)

    Calculating Net Electric Field

    Ok, so E1= http://www.texify.com/img/%5CLARGE%5C%21%288.987E9N/C%2A8.36E-6C%29/.0274%5E2m.gif E1= 1.0007E8 N/C E2= http://www.texify.com/img/%5CLARGE%5C%21%288.987E9N/C%2A20.2E-6C%29/.0905%5E2m.gif E2= -2.216E-7 N/C And Enet = E1+E2 Enet= 7.79E7N/C But that wasn't right. Am I correct using...

    Calculating Net Electric Field

    I think the mC meaning microC is just my weird homework interface. When I calculate the individual electric fields, is q always positive? I know it is in Coulomb's Law calculations.

    Calculating Net Electric Field

    Homework Statement Two charges are placed on the x axis. One charge (q1 = +8.36mC (microC)) is at x1 = +2.74cm and the other (q2 = -20.2mC (microC)) is at x1 = +9.05cm. Calculate the net electric field at x = 0cm. Homework Equations E= kq/r^2 The Attempt at a Solution I tried...
