The value of electric potential at any point due to any electric dipole is:-
A
$$ k\dfrac { \overrightarrow { P } \times \overrightarrow { r } }{ r^ 2 } $$
B
$$ k\dfrac { \overrightarrow { P } .\overrightarrow { r } }{ r^ 2 } $$
C
$$ k\dfrac { \overrightarrow { P } .\overrightarrow { r } }{ r^ 3 } $$
D
$$ k\dfrac { \overrightarrow { P } \times \overrightarrow { r } }{ r^ 3 } $$
Correct option is D. $$ k\dfrac { \overrightarrow { P } .\overrightarrow { r } }{ r^ 3 } $$
