Suppose you have a metallic sphere, that is not completly full from the middle, that is, the sphere is a shell. Suppose we put another metallic sphere (but that is not a shell) in the middle of the metallic shell (and without touching the two spheres). Then we charge the outer sphere with a certain charge, say +x (where x is positive). Will the outer surface of the inner sphere get charged ? The way i see it, the outer surface of the inner sphere will get charged by induction (and have a negative charge), and the center of the inner sphere will be charged by a positive charge, am i concluding right ? Some people told me that this will not happen since the permitivity of the metal (epsilon) will be too high, what do you think ? Thanks.
