Question

Use the following figure to answer the next problem: -A solid sphere of radius a is concentric with a hollow sphere of radius b,where b > a.If the solid sphere has a charge +Q and the hollow sphere a charge of -Q,the electric field at radius r,where a < r < b,is which of the following,in terms of k = (4$\pi\varepsilon$₀)^-1? A)kQ/r² B)2kQ/r² C)kQ/a² D)kQ/b² E)kQ/(b - a)²

Quizplus · Accepted Answer

The electric field at a point inside a conducting material is zero, so the charge on the hollow sphere does not contribute to the electric field at radius r (where a < r < b). The electric field due to the solid sphere of charge +Q at a distance r from its center is given by kQ/r^2, following Coulomb's law.
