Question

(6%) Problem 11: A conducting spherical shell of inner radius R1 and outer radius R2 has a point charge +q located at its center. The spherical shell has a net charge of taq Otheexpertta.com 33% Part (a) Enter an expression for the surface charge density on the inner surface of the spherical shell. 33% Part (b) Enter an expression for the surface charge density on the outer surface of the spherical shell 33% Part (c) The electric field at the surface points radially outward and has a magnitude of 7100 NC If R1 0.5 m Rs 1,5 m, and 2, what is q, in coulombs? Grade Summary Deductions96 q=8.875 * 10-71 4%

Explanation / Answer

E = k( q + aq) / R22

71000 = (9 x 109) (3) q / (1.5)2

=> Charge, q = 5.92 x 10-6 C
