Physics · JEE | Electrostatic Potential and Capacitance

हिन्दी

At a large distance \( r \), the electric potential \( V \) due to an electric dipole varies as:

  1. A
    \( \frac{1}{r} \)
  2. B
    \( \frac{1}{r^3} \)
  3. C
    \( \frac{1}{r^2} \)
  4. D
    Independent of \( r \)
View Answer & Solution

Correct answer · Option C

\( \frac{1}{r^2} \)

Explanation

The potential due to a dipole falls off as \( 1/r^2 \), unlike a single point charge whose potential falls off as \( 1/r \).
