Choose the correct relation regarding potential of an electric dipole. Here A, B, C and D all are at equal distance from point O which is much larger than the dimensions of the dipole. Then
= =
A and B are axial points
|VA| = |VB| = Kpr2 cos 0∘
= Kpr2
C and D are equatorial points. Thus,
VC = VD = Kpr2 cos 90∘
= 0
