An insulating spherical shell of inner radius r1 and outer radius r2 is charged so that its volume charge density is given by s(r) = 0 for 0<=r<=r1;s(r) = A/r for r1 <= r<=r2; s(r) = 0 for r > r2; where A is a constant and r is the radial distance from the centre of the shell. Find the electric field due to the shell throughout all space.

Solution:
An insulating spherical shell of inner radius r1 and outer radius r2 is charged
