Solve the given parts of following problem:
Problem: A hollow metal sphere has 7cm and 11cm inner and outer radii, respectively. The surface charge density on the inside surface is 200nC/m2. The surface charge density on the exterior surface is +200nC/m2.
Part I: What is the direction and strength of the electric field at point 4 cm from the center?
Part II: What is the direction and strength of the electric field at point 8 cm from the center?
Part III: What is the direction and strength of the electric field at point 12 cm from the center?
Please show all work and steps to determine the direction and strength of the electric field.
