PHY 102 Gauss's Law and Electrostatic Fields Objective Question
Take CBT

Question

What is the electric field just outside a charged conducting sphere (radius a, total charge Q)?
Options
A E = 0
B E = Q/(4πε₀a²)
Correct Answer
C E = σ/(2ε₀)
D E = constant inside
Correct Answer

Option B is the correct answer.

Detailed Explanation

Just outside a conducting sphere, E = Q/(4πε₀a²), which is the same as a point charge Q at the center.

Hint

Field at surface = Q/(4πε₀R²).
