Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
Electric field intensity (E) due to a single charge $ E \propto \frac{1}{r^2}$
Electric field intensity due to electric dipole is $ E \propto \frac{1}{r^3}$
Electric potential (V) due to a single charge $ V \propto \frac{1}{r}$
Electric field intensity due to a quadrupole $ E \propto \frac{1}{r^4}$
