As we have learned

if r>>l -

E_{axi}=\frac{1}{4\pi \epsilon _{0}}\frac{2P}{r^{3}}

V_{axi}=\frac{1}{4\pi \epsilon _{0}}\frac{P}{r^{2}}

- wherein

Angle between Eaxi and P is 0.

 

 E_{equatorial}= \frac{kp}{r^3} i.e E\propto p..and .. E\propto r^{-3}

 


Option 1)

p^{-1}..and ..r^{-2}

Option 2)

p..and ..r^{-2}

Option 3)

p^{2}..and ..r^{-3}

Option 4)

p..and ..r^{-3}
