Consider a little electric dipole (like e. g., a polar molecule) with a charge +q (q > 0) a) [10 pts] determine the electric field e for points along the y-axis. briefly discuss how b) [12 pts] for your solution in part a) consider the limit l/d, i. e. a point along the located at r--d and another charge -q which is located at x - d the direction of your result for e makes sense. axis very far away: y- » define e as a function of y and d, such that e is a small quantity and expand your solution in power series up to fourth order in €. show that the units of your power series' answer are correct » for what values of y does your expansion converge? ·why doesn't your solution behave like coulomb's law, i. e., why isn't el x 1/w2 here?
