Chapter 22, Problem 77EAP
To determine
a)Expression for the net force exerted on the dipole by the by charge +Q
b) Force toward +Q or away from +Q
c) Show that your expression from part a can be written, Use the binomial approximation
(1 + x) −n ≈ 1 – nx if x≪ 1.
d) How can an electric force have an inverse-cube dependence? Doesn’t Coulomb’s law say that the electric force depends on the inverse square of the distance? Explain
