An electric dipole, consisting of charges of magnitude 10.0 nC separated by 15.1 ?m, is in an electric field of strength 1520.0 N/C. What is the magnitude of the electric dipole moment?
What is the difference in potential energy corresponding to
dipole orientations parallel to and 45 degrees to the
field?
P = q*l = 10e-9*15.1e-6 = 1.51e-13 Cm
---------------
dU = P*E*(1-cos45) = 6.72*10^-11 J
The electric dipole moment is
p = q ( L) = 10 * 10 ^-9 C (15.1 * 10 ^-6 m) = 1.51 * 10 ^ -13 Cm
the difference in potential energy is
del U = Ui- Uf= pE cos theta - pE cos theta = pE ( cos 0-cos 45 )
=1.51 * 10 ^ -13 Cm(1520 N/C) ( 1- 0.707 )
=672.4936* 10 ^ -13 J
