Physics · Electrostatic Potential
हिन्दीThe electric potential due to a short electric dipole at a distance \( r \) along its axial line varies as:
Correct answer · Option 2
\( V \propto \frac{1}{r^2} \)
Explanation
The potential due to a dipole on its axis is given by \( V = \pm \frac{1}{4\pi\varepsilon_0} \frac{p}{r^2} \), so \( V \propto \frac{1}{r^2} \).
