Two equal charges 
of opposite sign separated by a distance 
constitute an electric dipole of dipole moment 
. If 
is a point at a distance r from the center of the dipole and the line joining the center of the dipole to this point makes an angle 
with the axis of the dipole, then the potential at 
is given by 
(Where 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For the given situation, diagram can be drawn as follows
As shown in figure component of dipole moment along the line OP will be 
. Hence electric potential at point P will be
