the field falls off, at large distance, not as
1/r 2 (typical of field due to a single charge)
but as 1/r3 We, now, determine the electric
potential due to a dipole and contrast it
with the potential due to a single charge As before, we take the origin at the
centre of the dipole Now we know that the
electric field obeys the superposition
principle
