Our text claims that a charged particle exerts a net attractive force on an electric dipole. The purpose of this exercise is to investigate this phenomenon. Suppose a permanent dipole is situated at the origin of the r-z plane and consists of charges +???? and −???? separated by a fixed distance ????. The dipole is situated such that +???? lies at − ???? 2 on the r-axis and −???? lies at ???? 2 on the r-axis. A charge +???? is situated at distance r from the center of the dipole on the positive raxis. We’ll assume, as is usually the case for electric dipoles, that ???? ≪ ???? for this configuration. a. (1 point) Draw a pictorial representation of this physical situation and label any quantities of interest. b. (2 points) Write an expression for the net force exerted on the dipole by charge +????. c. (1 point) Is this force toward +???? or away from +????? Explain. d. (3 points) Use the binomial expansion as an approximation tool to understand the effect that ???? ≪ ???? has on the physical situation. The binomial approximation to first order is wr
