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 3.62×10^6 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

Φ = Q_enc/ε₀ = (15+17)×10^-6 / 8.85×10^-12 = 3.62×10^6 Nm²/C.

Hint

Use Gauss's law: Φ = Q_enc/ε₀.
