Points$)$ A spherical shell is constructed in three concentric layers. The first layer has an iner radius A$,$ an outer radius B$,$ and a non$-$uniform charge densily cos nr$)+70$ where nando are constants. The second layer is a charged conductor with an inner radius C$,$ an outer radius D$,$ and a total charge $73$ where $3$ is a constant. The final layer has an inner radius E$,$ an outer radius F$,$ and a uniform charge density such that the electric fieldfor r $>$ F is zero.What is the total charge contained in the first layer of the structure?What is the charge on the outer layer of the second layer $($the conducting layer$)?$c$.$ What is the charge density in the third layer?d$.$ What is the magnitude of the electric field strength for A
