What is the work done in rotating a dipole from its unstable equilibrium to stable equilibrium ? Does the energy of dipole increase or decrease ?
1)Total work done is given by the equation W= -pE(Cos?2-Cos?1) ;Where ?2 is the angle at which dipole in unstable equilibrium =1800 and ?1 is the angle at which dipole is in stable equilibrium 00.
2)The negative sign shows that the dipole decreases in this process.
