PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question

Question

What is the electric field inside a thin spherical shell that carries a uniform net charge Q?
Options
A E = kQ/r²
B E = Q/ε₀
C E = 0
Correct Answer
D E = σ/2ε₀
Correct Answer

Option C is the correct answer.

Detailed Explanation

By applying Gauss's Law with a surface inside the shell (r < r₀), we find no enclosed charge, therefore the electric field is zero inside.

Hint

No charge is enclosed by a surface smaller than the shell.
