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 +...
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...
