Volume charge density at radius r=0.85 m (pic was posted sideways)Hi, what is the answer for part B? I tried the formula with the enclosed charge but no luck.

spherical shell charge Consider a spherical shell with inner radius .= 0 and outer radius r, = 1.2 m. The hollow inside the shell contains no charge: and change is distributed on the inside surface of the shell and within the shell itse that the electrical field inside the shell itself is everywhere outward pointing and of uniform cong he magnitude 35 N/d! 10p 2a What is the charge per unit area on the inner surface att= 1R (Please answer in SI unit and mul aly youranswer by doing Answer 3.0975 Updated 4 days ago Show feedback 1.0p 26 What is the charge per unit volume at radius i = 0185 m (within the material of the shell)?
