Introducing a metallic rod into an electric field. an uncharged thin metallic rod is introduced into a uniform electrostatic field, of intensity vector eo, in free space, such that it is either perpendicular or parallel to eo, as indicated in fig. q1.15. the rod affects the original field (a) less in case (a). (b) less in case (b) (c) equally noticeably in both cases. (d) negligibly in both cases. eo figure q1.15 introducing an uncharged thin metallic rod into a uniform electric field (eo denotes the original field intensity vector, before a new electrostatic state is established); for question 1.21.
