a) Calculate the electric field of a point P on the perpendicular bisector of a dipole. Also calculate the potential difference from infinity of the point. Also make a sketch of the equipotential lines and the electric field lines. b) Explain what happens if we put a large point charge Q at that point P.
a) Calculate the electric field of a point P on the perpendicular bisector of a dipole.
potential difference from infinity of the point is nothing but the negative of the expression obtained below since, the electric potential at infinite distance from the dipole is Zero.
b) if we put a large point charge Q at that point P, the resultant electric field would be parallel to the dipole and the direction would be from +ve to -ve charge.
