PHY 102 Gauss's Law and Electrostatic Fields Objective Question

Question

What is the electric field at the center of a uniformly charged solid non-conducting sphere?
Options
A Maximum
B Zero
Correct Answer
C Q/(4πε₀a²)
D Infinite
Correct Answer

Option B is the correct answer.

Detailed Explanation

At the center (r = 0), the enclosed charge is zero, so E = 0 for a uniformly charged solid sphere.

Hint

Symmetry gives zero field at center.
