Consider a spherical charge configuration consisting of a charged semiconducting sphere placed inside of a charged spherical shell. The semiconducting sphere has a volume charge density of py = 108(r/a)³ Cm³where r is the radial variable and a is the radius of the sphere. The shell has a radius b (b>a) and the electric flux density outside of the shell is D=0 Cm?. If a=8 m and b=3.9 m what is the surface charge of the conducting shell. a. -605.92 Cm-2 O b. -454.44 Cm-2 C. -787.69 Cm-2 d. -393.85 Cm-2 e. -908.88 Cm-2
