I'm stuck on a Electrostatic problem which I just don't seem to get.
The left-hand sphere has a positive charge Q and the right-hand sphere has a negative charge -Q. Charge is distibuted uniformly over each of two spherical volumes with radius . One sphere of charge is centered at the origin and the other at x = 2R
Find the magnitude of the net electric field at the point on the x-axis.
I did the first part already where it wanted the field at the orgin which was simple:
Q/(4*pi*epislon_0*(2R)^2)
but if I try the same method for this one it doesn't seem to work. I wanted to add them together I tried:
Q/(4*pi*epislon_0*(.5R)^2) + Q/(4*pi*epislon_0*(3R/2)^2)
but doesn't like it.
Thanks
