capacitors by b555

the space between the parallel plates of a cpacitor is filled with a dielectric.each molecule of the dielectric is assumed to have the form of a dumbbell with a length `l`l whose ends carry +q and -q. the number of molecules per cc is `n`.let us further assume that all the molecules have turnedalong the electric field under its action.find the intensity `E` of the field inside the capacitorfilled with the dielectric if before if before filling it the intensity of the electric field was E1
