Question

Two capacitors A and B with capacities C subscript 1 end subscript and C subscript 2 end subscript are charged to potential difference of V subscript 1 end subscriptandV subscript 2 end subscript, respectively. The plates of the capacitors are connected as shown in the figure with one wire free from each capacitor. The upper plate of A is positive and that of B is negative. An uncharged capacitor of capacitance C subscript 3 end subscript and lead wires falls on the free ends to complete circuit, then

  1. The final charge on each capacitor are same to each other    
  2. The final sum of charge on plates a and d is C subscript 1 end subscript V subscript 1 end subscript    
  3. The final sum of charge on plates b and g is C subscript 2 end subscript V subscript 2 end subscript minus C subscript 1 end subscript V subscript 1 end subscript    
  4. Both (b) and (c) are correct    

The correct answer is: Both (b) and (c) are correct
