Question

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

• A. 3
• B. -3
• C. 2
• D. -2

Answer 1

Answer: (B)

-3

Answer 2

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 , $E \propto \frac{1}{r^{3}}$
