Electric Forces and Electric Fields 27 15.53 Because of the spherical symmetry of the charge distribution, any electric field present will be radial in direction. If a field does exist at distance R from the center, it is the same as if the net charge located within were concentrated as a point charge at the center of the inner sphere. Charge located at does not contribute to the field at . rR > = ±²³³´µ¶ ·²³³´µ¶ ¸²³³´µ¶ ¹º²³³´ ± » ¼¸²³³´ ± » (a) At 1.00 r = , cm 0 E = since static electric fields cannot exist within conducting materials.
