A solid nonconducting sphere of radius R carries a uniform charge density throughout its volume. At a radial distance r1 = R/4 from the center, the electric field has a magnitude E₀. What is the magnitude of the electric field at a radial distance r₂ = 2R? A) E₀/4 B) zero C) E₀/2 D) E₀ E) 2E₀

Gauss's law states that the electric field outside a uniformly charged sphere is the same as if the entire charge were concentrated at the center of the sphere. Therefore, the electric field at a radial distance r2 = 2R is the same as the electric field at a radial distance r1 = R/4, which is E0.
