Consider a little electric dipole (like e. g., a polar molecule) with a charge +q (q > 0) located at
x = −d and another charge −q which is located at x = d.
a) [10 pts] determine the electric field e for points along the y-axis. briefly discuss how the
direction of your result for e makes sense.
b) [12 pts] for your solution in part a) consider the limit |y| » d, i. e. a point along the
y-axis very far away:
• define e as a function of y and d, such that e is a small quantity and expand your
solution in a power series up to fourth order in e.
• 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 |e| ∝ 1/y2
here?

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.
