a. What is the total charge on the exterior of the inner sphere?

b. What is the total charge on the inside surface of the hollow sphere?

c. What is the total charge on the exterior surface of the hollow sphere?

ine figure below snows a solla metal spnere at the centre or a nollow metai spnere. Ine radius or the solla metal sphere is 4.30cm, the inner radius or the nollow spnere is 9.0cm, and the oute radius of the hollow sphere is 12.7cm. The electric field (shown on the diagram) inside the hollow sphere, at a distance of 6.97cm from the centre of the solid metal sphere, has a magnitude of 14420N/C. The strength of the electric field at a point 20.8cm from the centre of the solid metal sphere is also 14420N/C. Conducting spheres
