Match List I with List II

LIST I (Quantity)		List – II (Variation with distance 'r')
(A)	Electric field intensity (E) due to a single charge	(I)	$\alpha \frac{1}{r}$
(B)	Electric field intensity due to electric dipole	(II)	$\alpha \frac{1}{r^4}$
(C)	Electric potential (V) due to a single charge	(III)	$\alpha \frac{1}{r^3}$
(D)	Electric field intensity due to a quadrupole	(IV)	$\alpha \frac{1}{r^2}$

Choose the correct answer from the options given below:

Options:

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

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

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

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

Correct Answer:

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

Explanation:

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}$
