Question
an electric dipole in x-y plane has dipole moment p which makes an angle θ with respect to positive x-axis. whe sujectd to an eletric feild E1=E icap it experiences torqe ζ1=a kcap. when subjected to another electric feild E2=1/root3 E1 jcap it experiences a torqueζ2=-ζ1. the potential energy associated with dipole when subjected to electric feild E1=Eicap will be
