Question

Intensity of an electric field E due to a dipole, depends on distance r as: (A) E propto (1/r4) (B)  E propto (1/r3) (C)  E propto (1/r2) (D)  E propto (1/r)

Tardigrade Admin · Accepted Answer

Here: Electric field =E Distance =r The electric field intensity due to dipole is E=(1/4 π ε0) × (2 p/r3) propto (1/r3)

Q. Intensity of an electric field $E$ due to a dipole, depends on distance $r$ as:

$E \propto \frac{1}{r ^{4}}$

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

$E \propto \frac{1}{r ^{2}}$

$E \propto \frac{1}{r}$

Here: Electric field $= E$
Distance $= r$
The electric field intensity due to dipole is
$E = \frac{1}{4 π ε _{0}} \times \frac{2 p}{r ^{3}} \propto \frac{1}{r ^{3}}$

Q. Intensity of an electric field E due to a dipole, depends on distance r as:

E∝r41​

E∝r31​

E∝r21​

E∝r1​
