Question

an electric deipole consists of points charges q1 = +12 nC and q2 = -12nC placed 10 cm apart compute the electric potentials at a point a,b and c

Answer 1

Answer

Electric field due to any electric dipole is given by

$V=\frac{kPcos\theta}{r}$

On axis V=$\frac{Kp}{r}$

Zero electrostatic potential due to an electric dipole at an equatorial point.

Where dipole moment

$P=qd\\=12*10^{-9}*0.1\\=1.2*10^{-9}C.m$
