The inner gray shaded circle shown represents a cross-sectional view of an insulating sphere of radius 10 cm with a total charge of +65 nC distributed uniformly throughout. Surrounding this sphere is an insulating spherical shell (outer blue shaded ring) with a total charge of -65 nC distributed uniformly throughout. There is empty space between the inner gray sphere and blue spherical shell as well as outside of the blue spherical shell. The inner radius of the blue spherical shell is 25 cm and the outer radius is 30 cm. The magnitude of the electric field is to be determined at each of the positions indicated. a.) (1 point) What is the electric field at point A (7 cm from center of inner sphere)? b.) (1 point) What is the electric field at point B (18 cm from center of inner sphere)? c.) (1 point) What is the electric field at point C (28 cm from center of inner sphere)? d.) (1 point) What is the electric field at point D (40 cm from the center of the inner sphere)?
