    Expression for the magnitude of an electric field

    Thank you. I'm just wondering, the problem says q1 is greater than q2, and both are positive, so wouldn't I subtract E1-E2? Do I integrate both and then subtract?

    Expression for the magnitude of an electric field

    k(q_1-q_2)/(R^2+x^2)^3/2

    Help with Coulomb's law: Net electrostatic force

    That makes perfect sense. Thank you.

    Help with Coulomb's law: Net electrostatic force

    I tried to explain it further in my reply to haruspex.

    Help with Coulomb's law: Net electrostatic force

    these are my equations. Basically in terms of a right triangle, I used the "legs" to calculate for each vector component instead of the hypotenuse as the whole force.

    Help with Coulomb's law: Net electrostatic force

    Right, I tried that answer and it was marked wrong, so I tried finding the force for the individual vector components (table in the lower left), by using just the distance in the x and y directions, but in meters in place of "d" for d^2. Then I added the components (i of q2 + i of q3, j of q2 +j...

    Help with Coulomb's law: Net electrostatic force

    Thank you! I tried uploading a picture of my work but I couldn't figure out how to initially. Also here's the original problem in all it's glory.

    Help with Coulomb's law: Net electrostatic force

    I tried just calculating the force with Coulomb's law, then calculating the forces for each vector individually and adding, but I got it wrong both ways
