Question

What is the correct SI unit of electric flux, φ?
Options
A N.m.C⁻¹
B N.m².C⁻¹
Correct Answer
C N.m.C⁻²
D N.m²
Correct Answer

Option B is the correct answer.

Detailed Explanation

Electric flux Φ = E·A, and since E is measured in N/C, flux has units of N·m²/C (equivalently N·m²·C⁻¹).

Hint

Multiply the SI unit of electric field (N/C) by area (m²).
