7 DETAILS SERPSE10 24.XP.013. MY NOTES ASK YOUR TEACHER Consider two thin, conducting, spherical shells as shown in cross-section in the figure. The inner shell has a radius r, = 11.0 cm and a charge of 24.0 nC. The outer shell has a radius 2 = 30.0 cm and a charge of -15.0 nC. Let A = 8.0 cm, B = 23.0 cm, and rc = 38.0 cm. B C (a) Find the electric field (E) at A, B, and C. EA = V/m EB = 1/m EC= V/m (b) Find the electric potential (V) at A, B, and C, with V = 0 at r = co. = VB = VC=
