Question

(a) Calculate the surface charge densities on the inner(sa) and outer(sb) surfaces of thespherical shell.

sa =

sb =

(b) Calculate the net radial electric field component at thefollowing radii:

At r = 2 cm: Er =

At r = 4.5 cm: Er =

At r = 10 cm: Er =

QuestionDetails: QuestionDetails: A point charge of strength q1 = -2 µC islocated at the center of a thick, conducting spherical shell ofinner radius a = 4 cm and outer radius b = 5 cm.The conducting shell has a net charge of q2 = 5µC.
