Physics · Electrostatic Potential
हिन्दीThe electric potential at a point due to an electric dipole at a large distance \( r \) depends on the angle \( \theta \) between the position vector \( \mathbf{r} \) and dipole moment vector \( \mathbf{p} \) as:
Correct answer · Option 3
\( \propto \cos\theta \)
Explanation
The potential due to a dipole is given by \( V = \frac{p\cos\theta}{4\pi\varepsilon_0 r^2} \), which shows \( V \propto \cos\theta \).
