SATHEE: Electrostatics Question 310

Electrostatics Question 310

Question: The value of electric potential at any point due to any electric dipole is [MP PMT 2004]

Options:

A) $k . \frac{\vec{p} \times \vec{r}}{r^{2}}$

B) $k . \frac{\vec{p} \times \vec{r}}{r^{3}}$

C) $k . \frac{\vec{p} \cdot \vec{r}}{r^{2}}$

D) $k . \frac{\vec{p} \cdot \vec{r}}{r^{3}}$

Show Answer

Answer:

Correct Answer: D

Solution:

Potential due to dipole in general position is given by

$V = \frac{k . p \cos θ}{r^{2}}$

$\Rightarrow$ $V = \frac{k . p \cos θ r}{r^{3}} = \frac{k . (\vec{p} . \vec{r})}{r^{3}}$
