A solid conductor sphere of radius a = 1 m has a positive net charge of 3Q. The sphere is surrounded with a concentric spherical shell of inner radius b = 2 m and outer radius c = 3 m. The spherical shell has a negative charge (-Q).The charge Q is equal with 1 times 10-6C. What are the net charges on the surface of the sphere, inner surface of the shell and outer surface of the shell, respectively? What is the charge density oh each of the surfaces at point (a)? What is the electric field at the following distances from the center of the sphere: r = 0.5 m, 1.5 m, 2.5 m and 3.5 m? Sketch the electric field lines in all regions in which the field is different from zero.
