हिन्दीTwo point charges \( -q \) and \( +q \) are placed at a distance of \( L \), as shown in the figure. The magnitude of electric field intensity at a distance \( R \) (\( R \gg L \)) varies as:
Correct answer · Option 4
\( \frac{1}{R^3} \)
Explanation
For a dipole, the electric field at a large distance varies inversely with the cube of the distance, i.e., \( E \propto \frac{1}{R^3} \).
