19. Two metallic charged spheres whose radii are \( 20 cm \) and \( 10 cm \), respectively, have each \( 150 \mu C \) positive charge. The common potential after they are connected by a conducting wire is(a) \( 9 \times 10^{6} V \)(b) \( 4.5 \times 10^{6} V \)(c) \( 1.8 \times 10^{7} V \)(d) \( 13.5 \times 10^{6} V \) |

Answer» V = q / C = (150+150)×10-6 4πε0(20+10)×10-2 = 9 × 106 V So, Option (a) is correct. |
