Intensity of electric field due to a Dipole is given by E = (p / 4πε₀r³) √3cos²θ + 1. Find the proportionality of E.

1. E ∝ 1/r³
2. E ∝ 1/r²
3. E ∝ 1/r
4. E ∝ r³

Correct answer: E ∝ 1/r³

Solution

The given formula for the electric field intensity due to a dipole includes a term proportional to 1/r³. This indicates that the electric field decreases with the cube of the distance from the dipole.
