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 r < a,is which of the following,in terms of k = (4$\pi\varepsilon$₀)^-1? A)kQ/r² B)kQr/a³ C)kQ/a² D)kQ/b² E)zero

Quizplus · Accepted Answer

Inside a uniformly charged solid sphere, the electric field is proportional to the distance from the center, but since the solid sphere's charge is exactly canceled out by the hollow sphere's charge, the net charge inside any radius r < a is zero, leading to an electric field of zero.
