Question

The distance of the field point point on the axis of a small electric dipole is doubled.By what factor will the electric field due to the dipole change

Answer 1

For a short dipole,
electric field at an axial position is inversely proportional to the third power of distance b/w the centre of dipole and the point!!!

so, if the distance is doubled, electric field will reduce with a factor of 1/8 th times.
