Question

The electric potential due to a small electric dipole at a large distance r from the centre of the dipole of the potential to

Answer 1

$\bold{ans : \frac{1}{r^2}}$

we know, the formula of electric potential due to dipole at a distance r from the centre of the dipole is

$\bold{V=\frac{KPcos{\theta}}{r^2}}$

where , V is the electrical potential
K is the kappa's constant
θ is the angle between point of observation and axis of dipole.
r is the distance from the centre of the dipole.

Answer 2

Answer is : 1/r²

Explanation :
Electric dipole is an arrangement in which two equal and opposite charges are separated by small distance .

Electric potential due to dipole at a point away from the dipole is given by equation :

V=(1/4πε₀) Pcosθ/r²

As we can see that Electric potential is inversely proportional to r²

Hence. V α 1/r²
