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 .
