Question

The electric potential at a point on the axis of an electric dipole depends upon the distance r(>>a) of the point from centre of the dipole as: (A)  propto r  (B)  propto (1/r)  (C)  propto (1/r2)  (D)  propto (1/r3)

Tardigrade Admin · Accepted Answer

The electric potential at any point on the axis of electric dipole, V=(p/4π ε 0r2) or V propto (1/r2)

Q. The electric potential at a point on the axis of an electric dipole depends upon the distance $r (>> a)$ of the point from centre of the dipole as:

$\propto r$

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

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

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

The electric potential at any point on the axis of electric dipole, $V = \frac{p}{4 π ε _{0} r ^{2}}$ or $V \propto \frac{1}{r ^{2}}$

Q. The electric potential at a point on the axis of an electric dipole depends upon the distance r(>>a) of the point from centre of the dipole as:

∝r

∝r1​

∝r21​

∝r31​
