Question

The correct statement about electric dipole is

• A. The total charge of an electric dipole is non-zero
• B. The electric field of an electric dipole at far-off distances $ (r) $ varies as $ 1/r^{2} $
• C. The dipole moment vector of an electric dipole points from $ -q $ to $ +q $ .
• D. The electric dipole moment of $ CO_{2} $ molecule is non-zero electric field free region

Answer 1

Answer: (C)

(a) The total charge of an electric dipole is zero
(b) The electric field of an electric dipole at far-off distances $(r)$ varies as $\frac{1}{r^{3}}$
(c) The dipole moment vector of an electric dipole points from $-q$ to $q$
(d) The electric dipole moment of $CO_{2}$ molecule is zero in electric field free region
