Q1. Consider two fixed charges +Q and -Q, respectively at (d/2, 0, 0) and (-d/2, 0, 0). The

two charges appear as an electric dipole at distances d. In this problem, you will

numerically compute tracks for a positive charge +e traveling in the potential created

by the two fixed charges.

a.Argue that the motion of the +e charge is restricted to the x-y plane if

its initial velocity is in the x-y plane.

b.pick appropriate units for length, time and energy. Derive the dimensionless equations of

motion for the +e charge
