Q12. A thin spherical shell of radius 20 cm carries a charge of -5.0 nC distributed uniformly over its surface. At the center of the shell there is a point charge q. If the electric field at a distance of 10 cm from the center of the shell is 1.8x10³ N/C, find the magnitude of q. A) 2.0 nC B) 15 nC C) 3.0 nC D) 10 nC E) 18 nC
