Depict the orientation of the dipole in (i) stable, (ii) unstable equi

1.	Depict the orientation of the dipole in (i) stable, (ii) unstable equilibrium in a uniform electric field.
Answer» for a dipole in external Electric field U = -pEcosθ (i) when θ = 0, cosθ = 1, u = -pE Minimum potential energy dipole is in stable equilibrium (ii) when θ = π, cosθ = cosπ = -1, and u = pE (Maximum Potential Energy) dipole is in unstabie equilibrium.

Depict the orientation of the dipole in (i) stable, (ii) unstable equilibrium in a uniform electric field.

Answer»

for a dipole in external Electric field

U = -pEcosθ

(i) when θ = 0, cosθ = 1, u = -pE Minimum potential energy dipole is in stable equilibrium

(ii) when θ = π, cosθ = cosπ = -1,

and u = pE (Maximum Potential Energy)

dipole is in unstabie equilibrium.
