As we have learned

At equatorial Point -

E_{equi}= \frac{kP}{\left ( r^{2}+l^{2} \right )^{\frac{3}{2}}}

If r >> l

E_{equi}= \frac{1}{4\pi \varepsilon _{0}}\frac{P}{r^{3}}

V_{equi}= 0

 

- wherein

Angle between Eaxial and P is 180°.

 

 The direction of electric field at equatorial point A or B will be in opposite direction, as that of direction of dipole moment.

 


Option 1)

Will be parallel

Option 2)

 Will be in opposite direction

Option 3)

Will be perpendicular

Option 4)
