Question

The electric potential at a point on the axis of an electric dipole depends upon the distance r (> > a) of the point from centre of the dipole as

• (A) ∝ r
• (B) ∝ 1/r
• (C) ∝ 1/r²
• (D) ∝ 1/r³

Answer 1

The Correct Option is C

Explanation:
The electric potential at any point on the axis of electric dipole,$$V=\frac{p}{4\pi {\epsilon }_0{r}^2}$$or$$V\propto \frac{1}{r^2}$$
