Q. Electric intensity due to an electric dipole varies with distance $r$ as $E \propto r^n$ where n is

COMEDKCOMEDK 2006Electric Charges and Fields

Solution:

Electric intensity due to an electric dipole is given by
$E = \frac{1}{4\pi \in_{0}} \frac{p}{r^{3}} \, \, \, \, \, \, \, $ for $ r > > a $
or , $E \propto \frac{1}{r^{3}}$
