An electric dipole consisting of charges of magnitude 3.90 nC separated by 7.10µm is in an electric field of strength 1350 N/C.
a) What is the magnitude of the electricdipole moment?b) What is the difference between potential energies for dipoleorientations parallel to and antiparallel to Evec?
A good model for a radio antenna is a dipole. P1 is on the perpendicular bisector of the dipole, and P2 is along the axis of the dipole in the direction of dipole vector ˆp. P1 and P2 are both a distance 100m from the center of the dipole.
