What orientation of the dipole has the greatest electric potential energy? What orientation of the dipole has the greatest electric potential energy? when the dipole moment and the electric field are antiparallel when the dipole moment and the electric field are parallel when the dipole moment makes the 60∘ angle with the electric field when the dipole moment and the electric field are perpendicular

The orientation of the dipole has the greatest electric potential energy is when when the dipole moment and the electric field are anti parallel to each other at that time cosθ= -1

U = -pEcosθ

put θ=180

⇒cos180 = -1

Therefore, U = pE
