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 r > b,is which of the following,in terms of k = (4$\pi\varepsilon$₀)^-1?

Quizplus · Accepted Answer

For a point outside both spheres (r > b), the electric field is determined by the net charge enclosed by a Gaussian surface at radius r. Since the solid sphere has a charge of +Q and the hollow sphere has a charge of -Q, the net charge is 0, resulting in an electric field of zero.
