-The expression of-electric potential for dipole is - V-14-x3C0-x3F5-0pcos-x3B8-r2-where p-qd dipole moment-so-V-x221D-1r2-Ans-B-

The electric potential at a point on the axis of an electric dipole depends on the distance $r$ of the point from the dipole as
$\frac{1}{r}$
$\frac{1}{r^{3}}$
$r$
$\frac{1}{r^{2}}$

The expression of electric potential for dipole is , $V = \frac{1}{4 π ϵ_{0}} \frac{p cos θ}{r^{2}}$ where $p = q d$ dipole moment.

so, $V \propto \frac{1}{r^{2}}$

Ans:(B)

The electric potential at a point on the axis of an electric dipole depends on the distance r of the point from the dipole as 1r1r3r1r2

The expression of electric potential for dipole is , V=14πϵ0pcosθr2 where p=qd dipole moment. so,V∝1r2 Ans:(B)
