Question
Two point charges +q and −q are separated by a
distance 2a. The electric field at a point on the perpendicular bisector at distance r from center is proportional to:Solution
In this case, we have a classic electric dipole : two equal and opposite charges +q+ and −q- separated by a distance 2a. At a point on the perpendicular bisector (equatorial line), the electric field due to a dipole is perpendicular to the dipole axis and given by the formula:
