A solid copper (metallic) sphere has inner radius r1 = 5 cm and outer radius r2 = 6 cm. An electric charge q = 3.75 nC is placed on the copper shell. 1. Use Powerpoint to sketch and label a diagram showing the charged copper shell, along with the appropriate Gaussian surface for finding the electric field inside the shell. Il. Use Gauss's Law to find an expression for the electric field in the region r r2. Briefly explain how you've found this expression. IV. Calculate the electric field strength at a point 8 cm from the center of the shell. V. Sketch a plot of the electric field vs r, the distance from the center of the shell. Clearly label the axes and the points r = 1 and r = 2
