E5) A solid conducting sphere of radius 50 cm carries an electric charge of - 30 µC. a.) At what radius from the center of the sphere does the electric field have its maximum value? b.) For what values of the distance from the center is the electric field zero? c.) Use Gauss's law to find the expression for the electric field at a radius of 60 cm from the center of the sphere. What is the direction of the electric field vector at this position?
