Solve the all given parts of following problem:
Problem: A point charge Q = 6.30 x 10-6 C is at the center of a conducting spherical shell of radius R = 18.50 cm. The total charge of the shell is -6.30 x 10-6 C.
Part I: What is the field in the region between the point charge and the shell?
Part II: What is the field just outside the shell?
Please help for the above question, completely confused!! Show each steps if possible, Thanks.
