The figure shows a hollow conducting spherical shell with an inner radius of 8 cm and an outer radius of 10 cm. A charge, q, placed at the center of the shell causes an electric field at the inner surface of the shell, Ei𝐸𝑖 , which has a magnitude of 80 N/C and points toward the center of the sphere. The electric field at the outer surface, Eo𝐸𝑜 , has a magnitude of 80 N/C and points away from the center of the sphere. Determine the charge of the particle, q.  rev: 10_23_2013_QC_2344Multiple Choice+ 1.46 × 10−10 C+ 1.46 × 10-10 C0 C− 5.69 × 10−11 C- 5.69 × 10-11 C− 1.46 × 10−10 C- 1.46 × 10-10 C+ 5.69 × 10−11 C+ 5.69 × 10-11 C− 3.20 × 10−11 C- 3.20 × 10-11 C+ 8.89 × 10−11 C+ 8.89 × 10-11 C+ 3.20 × 10−11 C+ 3.20 × 10-11 C− 8.89 × 10−11 C
