Two equal charges $$q$$ of opposite sign separated by a distance $$2a$$ constitute an electric dipole of dipole moment $$p$$. If $$P$$ is a point at a distance $$r$$ from the centre of the dipole and the line joining the centre of the dipole to this point makes an angle $$\theta $$ with the axis of the dipole, then the potential at $$P$$ is given by $$(r2a)$$ (Where$$p=2qa$$) [MP PET 1997]

Question

Two equal charges $$q$$ of opposite sign separated by a distance $$2a$$ constitute an electric dipole of dipole moment $$p$$. If $$P$$ is a point at a distance $$r$$ from the centre of the dipole and the line joining the centre of the dipole to this point makes an angle $$\theta $$ with the axis of the dipole, then the potential at $$P$$ is given by $$(r>>2a)$$ (Where$$p=2qa$$) [MP PET 1997]
