A hollow non conducting spherical shell has outer radius

Reference no: EM13681754

A hollow non conducting spherical shell has outer radius r2 = 17cm and inner radius of r1= 6 cm. A charge of q = -25nC lies at the center of the shell. The shell carries a spherically symmetric charge density rho = Ar for R1 <r<R2 that increases linearly with radius, where A = 29uC/m4.
