Answer & Solution

Correct Answer

(D) A-IV, B-III, C-I, D-II

Step-by-step Solution

Detailed explanation

For a single charge, the electric field follows \(\frac{1}{r^2}\) while the potential follows \(\frac{1}{r}\). As you increase complexity to dipoles and quadrupoles, the field strength drops faster at \(\frac{1}{r^3}\) and \(\frac{1}{r^4}\) respectively. D) A-IV, B-III, C-I, D-II
