1. The problem statement, all variables and given/known data A certain electric dipole is placed in a uniform electric field E of magnitude 20 N/C. Figure 22-59 gives the potential energy U of the dipole versus the angle θ between E and the dipole moment P. What is the magnitude of P? 2. Relevant equations U=p(dot)E 3. The attempt at a solution Somehow there is an integral needed to solve this but I don't know where to start. there is also a graph with this question.
