PHY 102 Last Minute Prep Objective Question

Question

Two charges q₁=15μC and q₂=17μC are within a spherical surface radius 20cm. Calculate total flux through the surface. (ε₀=8.85×10⁻¹²)
Options
A 3.62×10⁶ Nm²/C
Correct Answer
B 3.62×10⁻⁶ C²N⁻¹m⁻²
C 3.62×10⁻⁶ Nm²/C
D 3.62×10⁻⁶ C²N⁻¹m⁻²
Correct Answer

Option A is the correct answer.

Detailed Explanation

Total Flux Φ = Q_enc / ε₀ = (15+17)×10⁻⁶ / 8.85×10⁻¹² = 3.62×10⁶ Nm²/C

Hint

Gauss's law states flux depends only on total enclosed charge.
