Solve the all parts of given problem:
Problem: Two hollow metal spheres are concentric with each other. The inner sphere has a diameter of 0.40 m and is at a potential of 105 V. The outer sphere has a diameter of 0.42 m and is at a potential of 100 V.
Part A: Find the electric energy contained in the space between the spheres.
Part B: Find the electric energy contained in this space if it is filled with a dielectric material of dielectric constant 3.0.
I need help to find the electric energy contained in the space between the spheres.
