Two capacitors C ₁ and C ₂ 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

Options

  1. A5 C₁=3 C₂
  2. B3 C₁=5 C₂
  3. C3 C₁+5 C₂=0
  4. D9 C₁=4 C₂

Correct answer

B. 3 C₁=5 C₂

Step-by-step solution

For potential to be made zero, after connection 120 C ₁=200 C ₂ [ C= q v ] 3 C₁=5 C₂
