Question

Two small electric dipoles each of dipole moment p are situated at (0, 0, 0) and (r, 0, 0). The electric potential at a point  is:

Answer 1

Correct option: (B) 0

Explanation:

As ON = MN = OM = r

So it is equilateral triangle : 

∴ Potential at N due to two dipoles ; 

V = V₁ + V₂

= 0
