Quiz # 3 Physics 230 Prof. Hadley 1. Question: NOTE : For the following questions, use k instead of epsilon sub zero. This gives Gauss' Law as: E*A*cos(theta) = 4*pi*k*( Q encl ) THE PROBLEM: Refer to Figure 1 below. You have a conducting spherical shell of radius R with total charge -Q on it. At the center is placed a point charge of +Q. If r is the variable used in E(r) for the radial coordinate, using Gauss' Law, answer the following questions : FIGURE 1 Question 1. What is the magnitude of the electric field for r < R?
