In the figure an electric dipole swings from an initial orientation i(θi = 24.1∘) to a final orientation f(θf = 24.1∘) in a uniform external electric field E→. The electric dipole moment is 1.76×10−27 C⋅m; the field magnitude is 2.75×106 N/C. What is the change in the dipole's potential energy? Number Units
