A spherical, non-conducting shell of inner radius r₁= 10 cm and outer radius r₂= 15 cm carries a total charge Q = 15 μC distributed uniformly throughout the volume of the shell. What is the magnitude of the electric field at a distance r = 12 cm from the center of the shell? (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²) A) 5.75 × 10³ N/C B) zero C) 2.87 × 10⁶ N/C D) 5.75 × 10⁶ N/C E) 2.87 × 10³N/C

At all points inside a uniformly charged shell, the electric field is zero. Therefore, the magnitude of the electric field at a distance of 12 cm from the center of the shell is zero, and the correct choice is (B).

A Spherical, Non-Conducting Shell of Inner Radius R1= 10 Cm
