Two capacitors A and B with capacities 3μF and 2μF are charged to a potential difference of 100V and 180V, respectively. The plates of the capacitors are connected as show in figure with one wire of each capacitor free. The upper plate of A is positive and that of B is negastive. An uncharged 2μF capcitor C with lead wires falls on the free ends to complete the circuit. Calculate a. the final charge on the three capacitors. b. the amount of electrostatic energy stored in the system before and after completion of the circuit.

Two parallel plate capacitors A and B have the same separation d = 8.85×10^−4 m between the plates. The plate area of A and B are 0.04 m^2 and 0.02 m^2 respectively. A slab of dielectric constant (relative permittivity) K = 9 has dimensions such that it can exactly fill the space between the plates of capacitor B. (i) The dielectric slab is placed inside. A as shown in figure (a). A is then charged to a potential difference of 110V. Calculate the capacitance of A and the energy stored in it. The battery is disconnected and then the dielectric slab is moved from A. Find the work done by the external agency in removing the slab from A. (iii) The same dielectric slab is now placed inside B, filling it completely, The two capacitors A and B are then connected as shown in figure(c). Calculate the energy stored in the system.
