A hollow metal sphere has an inner radius of 20.0 cm and an outer radius of 30.0 cm. Inside this sphere is a solid metal sphere with a radius of 10 cm. The electric field at r = 15 cm has a magnitude 1.00 x 10° N/C directed radially inwards and the electric field at r = 35 cm has a magnitude of 2.00 x10° N/C directed radially outward as shown. Enter all your answers with 2 decimal points. (a) The total charge on the inner sphere is µCoulombs. (b) The total charge on the inner surface of the hollow sphere is µCoulombs. (c) The total charge on the outer surface of the hollow sphere is µCoulombs. (d) The voltage difference between point a at r= 30 cm and point b at r = 0 cm is o cm b m kVolts. a
