Two capacitors, 3.0μF and 4.0μF, are individually charged across a 6.0V battery. After being disconnected from the battery, they are connected together with a negative plate of one attached to the positive plate of the other. What is the final charge on capacitors?(a) 2.6μC,3.4μC(b) 3.4μC,2.6μC(c) 2.6μC,2.6μC(d) 3.4μC,3.4μC

A solid conducting sphere of radius R is surrounded by a concentric metallic shell of inner radius 2R and outer radius 3R. The shell is earthed. The inner sphere is connected to a switch S by a thin conducting wire through a small hole in the shell. By closing the switch S, the inner sphere is connected to a distant conducting sphere of radius R having charge Q. Find the charge that flows to earth through wire AB.

Question No. 6Four parallel conducting plates W, X, Y and Z are arranged as shown in figure. Plates W,X and Z have plate area A and plate Y has area A/2. The distance between any two consecutive plates is 'd then capacitance of this system is: Gren dε0​⋅d​=35 i. F
