Positive Charge Q Is Placed on a Conducting Spherical Shell $\pi$

question 18

Multiple Choice

Positive charge Q is placed on a conducting spherical shell with inner radius R₁ and outer radius R₂. A point charge q is placed at the center of the cavity. The magnitude of the electric field produced by the charge on the inner surface at a point in the interior of the conductor a distance r from the center, is:

• A) 0
• D) q/4 \(\pi\)\(\varepsilon\)₀r²
• E) Q/4 \(\pi\)\(\varepsilon\)₀r²
