Electric fieid and eiectric potential at a general point at a distance r from the centre of the dipoie is Eg = ( 1/ 4 π ε0 ) ( P/ r3 ) √ ( 3 cos2 θ + 1) and Vg = ( 1/ 4 π ε0 ) ( p cos θ / r2 )

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

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

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

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

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

Electric fieid and eiectric potential at a general point at a distance r from the centre of the dipoie is
$E_{g} = \frac{1}{4 π ε _{0}} \frac{P}{r ^{3}} (3 co s^{2} θ + 1)$
and $V_{g} = \frac{1}{4 π ε _{0}} \frac{p cos θ}{r ^{2}}$
