Question

An electric dipole is placed in an uniform electric field with the dipole axis making an angle $\theta$ with the direction of the electric field. The orientation of the dipole for stable equilibrium is

• A. $\frac{\pi }{6}$
• B. $\frac{\pi }{3}$
• C. $0$
• D. $\frac{\pi }{2}$

Answer 1

Answer: (D)

$\frac{\pi }{2}$

Answer 2

For stability of equilibrium, the orientation of the dipole is $\frac{\pi }{2}$ .
