Detailed step-by-step solutions are vital for confirming your understanding of the end-of-chapter exercises. You can find resources on several platforms:
Alex first set up from Gauss’s law: ( D_r = Q/(4\pi r^2) ), then ( E_r = D_r/\varepsilon ). He integrated ( V = -\int_b^a E_r dr ) and got ( C = Q/V = 4\pi\varepsilon/(1/a - 1/b) ). engineering electromagnetics 5th edition hayt solutions
