4. An electric dipole consists of two point charges of equal magnitude, but opposite sign, separated by a short distance. The dipole is electrically neutral, but due to the separation of its charges gives rise to an electric field in its vicinity. Many molecules have charge distributions which can be approximated as an electric dipole, water being one of the most common. 2d Given an electric dipole as shown below, calculate the electric field at the point P. Hint: Start from Coulomb's Law.
