(Figure 3.51) shows two concentric conducting shells of radii `r_(1)` and `r_(2)` carrying uniformaly distributed charges `q_(1)` and `q_(2)`, respectively. Find an expression for the poptential of each the potential of each shell. . |

Answer» The potential of each sphere consists of two points : one due to its own charge, and the other due to the charge on the other sphere. Using the principle of superposition, we have `V_1 = V_(r_(1), "surface") + V_(r_(2), "inside")` and `V_2 = V_(r_(1), "outside") + V_(r_(2), "surface")` Hence, `V_1 = (1)/(4 pi epsilon _0) q_(1)/r_(1) + (1)/(4 pi epsilon_0) q_(2)/r_(2)` and `V_2 = (1)/(4 pi epsilon_0)q_(1)/r_(2)+(1)/(4 pi epsilon_0)q_(2)/r_(2)`. |
