There are two, thin sperhical shells, both of uniformly distributed charge. The center of the larger sphere is at <0, 0, 0>; it has a radius of 12 cm and a uniform positive charge of 7e-9 C. The center of the smaller sphere is at <25, 0, 0> cm; it has a radius of 3 cm and a uniform negative charge of -1e-9 C!
What is the electric field at location B (15 cm above the center of the small sphere)? Again, neglect the small contribution of the polarized molecules in the plastic, because the shells are very thin and don't contain much matter.
Plugged into Esphere=9e9(Q/r^2)rhat...found magnitude then unit vector but answer was wrong! Do you have to find angle using tangent, if so, explain or whatever! Thanks!
