Consider a conducting spherical shell with
inner radius b = 0.862 m and outer radius c =
1.21 m. There is a net charge q2 = 3.82 ìC
on the shell. At its center, within the hollow
cavity, there is a point charge q1 = 2.89 ìC.
Determine the flux through the spherical
Gaussian surface S1, which has a radius of
a = 0.294 m.
Answer in units of Nm2/C
