The equipotential curves due to a positive and a negative charge of the same magnitude separated by a distance of 1 m are circles. True or False.
Homework Answers
The positive and negative charge situated 1m apart so they makes a electric dipole p
So the potential due to this dipole is
V = k*p*cos(x) /r^2
So the curve of potential v is not a circle it is
