Question

Electric potential at an equatorial point of a small dipole with dipole moment p(r, distance from the dipole) is (A) (p/4 π ε0 r3) (B) (p/4 π ε0 r2) (C) zero (D) (2 p/4 π ε0 r3)

Electric potential at equatorial point of a small dipole moment

= P

(at

r

) As we have learned,
if,

r >> 1

E_{a x i} = \frac{1}{4 π ϵ _{0}} \frac{2 P}{r ^{3}}

V_{axi} = \frac{1}{4 π ϵ _{0}} \frac{P}{r ^{2}}

where, angle between

E_{a x i}

and

P

will be

O

.

Q. Electric potential at an equatorial point of a small dipole with dipole moment $p (r$ , distance from the dipole) is

$\frac{p}{4 π ε _{0} r ^{3}}$

$\frac{p}{4 π ε _{0} r ^{2}}$

zero

$\frac{2 p}{4 π ε _{0} r ^{3}}$

Electric potential at equatorial point of a small dipole moment
$= P$ (at $r$ ) As we have learned,
if, $r >> 1$
$E_{a x i} = \frac{1}{4 π ϵ _{0}} \frac{2 P}{r ^{3}}$
$V_{axi} = \frac{1}{4 π ϵ _{0}} \frac{P}{r ^{2}}$
where, angle between $E_{a x i}$ and $P$ will be $O$ .
