Match List - I with List - II.
| List – I | List – II | ||
|---|---|---|---|
| (A) | Electric Field Intensity | (I) | Coulomb/metre |
| (B) | Electric dipole moment | (II) | Newton metre2/Coulomb |
| (C) | Linear charge density | (III) | Newton/Coulomb |
| (D) | Electric flux | (IV) | Coulomb metre |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Each unit follows from the definition of the quantity.
(A) Electric Field Intensity — this matches (III) Newton/Coulomb. The field is the force per unit charge, \( E = F/q \).
(B) Electric dipole moment — this matches (IV) Coulomb metre. It is charge times separation, \( p = q\,(2a) \).
(C) Linear charge density — this matches (I) Coulomb/metre. It is charge per unit length, \( \lambda = q/l \).
(D) Electric flux — this matches (II) Newton metre2/Coulomb. It is the field times the area, \( \phi = EA \), that is \( \mathrm{N\,C^{-1}}\times\mathrm{m^{2}} \).
