Question

Two charges q1 = 15µC and q2 = 17 µC are within a spherical surface of radius 20cm. Calculate the total flux through the surface. (ε₀ = 8.85×10⁻¹² C²/N·m²)
Options
A 3.62 × 10⁶ Nm²/C
Correct Answer
B 3.62 × 10⁻⁶ Nm²/C
C 3.62 × 10⁶ C/Nm²
D 3.62 × 10⁻⁶ C/Nm²
Correct Answer

Option A is the correct answer.

Detailed Explanation

Φ = Q_enclosed/ε₀ = (15+17)×10⁻⁶ / 8.85×10⁻¹² = 32e-6 / 8.85e-12 = 3.616 × 10⁶ Nm²/C.

Hint

Gauss's law: Φ = Q/ε₀.
