The figure shows two concentric conducting thin spherical shells: • Sphere-A of radius RA = 20 cm and a total charge QA = -4 × 10-¹² [C]. Sphere-B of radius RB = 5 cm and a total charge QB = 1.2 × 10-¹¹ [c]. B RB d) What is the magnitude of the electric field at r = 19 cm from the center of the spheres? + [N/C] Select the correct answer from the list: E = e) What is the magnitude of the electric field at r = 4 cm from the center of the spheres? + [N/C] Select the correct answer from the list: E = 0 f) What is the net electric flux through the spherical surface of radius r = 4 cm from the center of the spheres? + [N.m²/C] Select the correct answer from the list: ϕ = 0
