Potential Energy of a dipole in an external field
r – position vector V( r) – external potential at point r r 1 & r 2 – position vectors
V( r 1) & V( r 2) – external potential at point r 1 & r 2
Potential Energy of a dipole in an external field
Dipole in an external field experiences a torque which tries to align it in the direction of the electric field. The work done to oppose this force gets stored in the form of potential energy.
