Answer:
Let the dipole is kept in two positions (a) and (b) in constant electric field E
o
as shown in the figure.
Case (a) : Angle between dipole and the electric field θ=0
o
Potential energy of dipole U=−PE
o
cosθ
∴ U=−PE
o
cos0
o
=−PE
o
Thus the dipole is said to be in stable equilibrium.
Torque τ=PE
o
sinθ
∴ τ=PE
o
sin0
o
=0
Case (b) : Angle between dipole and the electric field θ=180
o
Potential energy of dipole U=−PE
o
cos180
o
=PE
o
Thus the dipole is said to be in unstable equilibrium.
Torque τ=PE
o
sin180
o
=0
