Physics · Electrostatic Potential
हिन्दीIf the distance \( r \) from an electric dipole is very large compared to its length \( 2a \) (\( r \gg a \)), how does the electrostatic potential \( V \) vary with distance \( r \)?
Correct answer · Option 3
\( V \propto \frac{1}{r^2} \)
Explanation
For a dipole, potential falls off as \( 1/r^2 \), unlike a single charge where it falls off as \( 1/r \).
