Positive charge Q is placed on a conducting spherical shell with inner radius R1 and outer radius R2. A point charge q is placed at the center of the cavity. The magnitude of the electric field at a point outside the shell, a distance r from the center, is: Q 4πε0(R12 − r2) (q+Q) 4πε0(R12 − r2) Q 4πε0R12 q 4πε0r2 (q+Q) 4πε0r2
