Question

# The electric potential at a point on the axis of an electric dipole depends on the distance $$r$$ of the point from the dipole as

A
1r
B
1r2
C
r
D
1r3

Solution

## The correct option is D $$\cfrac { 1 }{ { r }^{ 2 } }$$ The expression of electric potential for dipole is , $$V=\dfrac{1}{4\pi\epsilon_0} \dfrac{p\cos\theta}{r^2}$$ where $$p=qd$$ dipole moment. so,$$V \propto \dfrac{1}{r^2}$$ Ans:(B) Physics
