List - I
(Physical Quantity)

List – II
(S.I. unit)

 (A)

 Linear charge density

 (I)

 Newton (metre)2 / coulomb 

 (B) 

 Electric dipole moment 

 (II)

 Coulomb / metre

 (C)

 Polarisation vector

 (III) 

 Coulomb / (metre)2

 (D)

 Electric flux

 (IV)

 Coulomb – metre

Choose the correct answer from the options given below:

Options:

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

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

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

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

Correct Answer:

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

Explanation:

Linear Charge density $\lambda = \frac{Q}{L} =Coulomb / metre $

 Electric dipole moment $ p = Q.L = Coulomb . metre $

Polarization Vector define as an average dipole moment, per unit volume, $ P = \frac{p}{V} = Coulomb / (metre)^2$

Electric flux $ \phi = E.A = Newton (metre)2 / coulomb$
