Electrostatics Question 232
Question: Two equal charges of opposite sign separated by a distance constitute an electric dipole of dipole moment . If is a point at a distance from the centre of the dipole and the line joining the centre of the dipole to this point makes an angle with the axis of the dipole, then the potential at is given by (Where ) [MP PET 1997]
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: A
Solution:
For the given situation, diagram can be drawn as follows component of dipole moment along the line OP will be
Hence electric potential at point P will be
