Which one is the correct expression of electric potential on the axial point of a dipole whose dipole moment is р and length is 2l, at a distance of r?

Three capacitances 3\(\mu\)F, 9\(\mu\)F, and 18\(\mu\)F are connected once in series and then in parallel. The ratio of equivalent Cs/Cр will be:

If V_A and VV_B are the potentials of the two points A and B, what will be the correct relation between the electric field and the potential difference between the points? The distance between the points is d.
