Answer

(a) $3.1\times10^{-9}\,C$ (b) $3.7\times10^{-8}\,J$

Work Step by Step

(a) Charge $q=CV=(\kappa C_{0})V=(2.6\times50\times10^{-12}\,F)24\,V$ $=3.1\times10^{-9}\,C$ (b) Energy $U=\frac{1}{2}CV^{2}=\frac{1}{2}\times(\kappa C_{0})\times V^{2}$ $=\frac{1}{2}\times2.6\times50\times10^{-12}\,F\times(24\,V)^{2}=3.7\times10^{-8}\,J$
