Physics · Electrostatic Potential

A short electric dipole with dipole moment \( \mathbf{p} \) is placed at the origin. The electric potential at a point \( P \) located at a distance \( r \) from the origin, where the position vector makes an angle \( \theta \) with the dipole moment vector, is given by:

1. A
   \( \frac{1}{4\pi\varepsilon_0} \frac{p \cos\theta}{r^3} \)
2. B
   \( \frac{1}{4\pi\varepsilon_0} \frac{p \cos\theta}{r^2} \)
3. C
   \( \frac{1}{4\pi\varepsilon_0} \frac{p \sin\theta}{r^2} \)
4. D
   \( \frac{1}{4\pi\varepsilon_0} \frac{p}{r^3} \)
