The electric field and the potential of an electric dipole vary with distance r as

Question

The electric field and the potential of an electric dipole vary with distance r as (A) (1/ r 2) and (1/ r 3) (B) (1/ r 3) and (1/ r 2) (C) (1/ r ) and (1/ r 2) (D) (1/r2) and (1/r)

E = K (2 p / r 3) propto (1/ r 3) V = K ( p cos θ/ r 2) propto (1/ r 2)

Q. The electric field and the potential of an electric dipole vary with distance $r$ as

$\frac{1}{r ^{2}}$ and $\frac{1}{r ^{3}}$

$\frac{1}{r ^{3}}$ and $\frac{1}{r ^{2}}$

$\frac{1}{r}$ and $\frac{1}{r ^{2}}$

$\frac{1}{r ^{2}}$ and $\frac{1}{r}$

$E = K \frac{2 p}{r ^{3}} \propto \frac{1}{r ^{3}}$
$V = K \frac{p c o s θ}{r ^{2}} \propto \frac{1}{r ^{2}}$
