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

Options

A. `(pi)/(6)`
B. `(pi)/(3)`
C. 0
D. `(pi)/(2)`

Answer

C

Explanation

For stable equilibrium, `theta = 0` i.e., electric dipole is aligned along the electric field.
