Question:

Match List-I with List-II

List-I Physical quantity

List-II Unit

(A) Electric flux

(I) $Vm^{-1}$

(B) Polarisation

(II) $kg\, m^{-1} s^{-2}$

(C) Electric field

(III) $V m$

(D) Energy density

(IV) $Cm^{-2}$

Choose the correct answer from the options given below:

Options:

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

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

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

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

Correct Answer:

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

Explanation:

The correct answer is Option (2) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

List-I Physical quantity

List-II Unit

(A) Electric flux

(III) $V m$

(B) Polarisation

(IV) $Cm^{-2}$

(C) Electric field

(I) $Vm^{-1}$

(D) Energy density

(II) $kg\, m^{-1} s^{-2}$
  • Electric flux = Electric field $\times$ area $\to$ unit = $V/m \times m^2 = Vm \to$ (III)
  • Polarisation = dipole moment per unit volume $\to$ unit = $C \cdot m/m^3 = C/m^2 \to$ (IV)
  • Electric field = force/charge $\to$ unit = $N/C = V/m \to$ (I)
  • Energy density = energy per unit volume $\to$ unit = $J/m^3 = kg \, m^{-1}s^{-2} \to$ (II)
