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°.

 

 V= \frac{p \cos \theta }{r^2}.. if \theta = 0\degree..then..V_a= max

 


Option 1)

90 \degree ..and.. 180 \degree

Option 2)

0 \degree ..and.. 90 \degree

Option 3)

90 \degree ..and.. 0 \degree

Option 4)

0 \degree ..and.. 180 \degree
