A solid nonconducting sphere (radius = 12 cm) has a charge of uniform density (30 nC/m³) distributed throughout its volume. Determine the magnitude of the electric field 15 cm from the center of the sphere. A) 22 N/C B) 49 N/C C) 31 N/C D) 87 N/C E) 26 N/C

Question

Quizplus · Accepted Answer

The electric field outside a uniformly charged sphere is calculated using Gauss's law. The total charge (Q) is the charge density (ρ) times the volume of the sphere. For a radius of 15 cm, the electric field E = kQ/r², where k is Coulomb's constant.
