question 65

Multiple Choice

$A solid sphere of radius a is concentric with a hollow sphere of radius b, where b > a. If the solid sphere has a uniform charge distribution totaling +Q and the hollow sphere a charge of -Q, the electric field at radius r, where r < a, is which of the following, in terms of k = (4 \pi\isin 0) -1? A) kQ/r2 B) kQr/a3 C) kQ/a2 D) kQ/b2 E) zero$ A solid sphere of radius a is concentric with a hollow sphere of radius b, where b > a. If the solid sphere has a uniform charge distribution totaling +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 $\pi$ $\isin$ ₀) ^-1?
