Question

A point charge q is kept on equatorial position of an
electric dipole of dipole Moment p at distance ras
shown in the figure. Electric potential at the centre of
dipole is
.
r
p
р​

Answer 1

Answer:

Correct option is

A

zero

Electric potential at equatorial point of a small dipole moment =P (at r)

As we have learned,

if, r>>1

angle between E

axi

and P will be O.
