Two capacitors C1 and C2 are charged to 120 V and 200 V respectively. It is found that by connecting them together the potential on each one can be made zero. Then:
  1. 3C1+5C2=0
  2. 9C1=4C2
  3. 5C1=3C2
  4. 3C1=5C2

Solution


For potential to be made zero, after connection

120C1=200C2

⇒3C1=5C2
