    Electric Potential Energy of A System of Point Charges

    A Particle of charge q=7.5x10^-6 Coulombs is released from rest at .6m on the x axis. The particle moves due to charge Q = -20x10-6 C. What is the Kinetic Energy of the particle the instant it has moved .4 meters if Q stays fixed at the origin? Here I used KE1 + U1 = KE2 + U2 Which equals 0 +...

    Net Electric Field of 2 charged particles fixed to X-axis

    Wait, so one of the r's should be .5m, the distance between the two particles?

    Net Electric Field of 2 charged particles fixed to X-axis

    2 Particles are fixed to an x-axis: q1=2.1*10^-8 C @ x=.2m q2=-4.00q1 @ x=.7m We are trying to find the coordinate on the x-axis where the net electric field produced by the particles = 0. The equation I have is E=((8.99*10^9)q)/r^2 I got what i thought was q2 first, by multiplying...
