Homework Statement
Two spherical shells have a common center. A -1.37 x 10-6 C charge is spread uniformly over the inner shell, which has a radius of 0.0422 m. A +5.86 x 10-6 C charge is spread uniformly over the outer shell, which has a radius of 1.60 m. Find the magnitude of the electric field at a distance (measured from the common center) of (a) 0.200 m (b) 0.100 m, and (c) 0.025 m.
Homework Equations
Honestly I'm not sure how to set this equation up.
I have calculated the Electric Field of each sphere. the smaller is 6.92*106 and the larger is 2.06*104
I also calculated the Electric Flux each. The smaller being 6.54*104 and the larger being 6.63*105.
Now I'm not quite sure if I have to add the two spheres together, or what to do since the inside sphere is negatively charged.
