Q. Two capacitors $C_{1}$ and $C_{2}$ are charged to $120 V$ and $200 V$ , respectively. It is observed that by connecting them together, the potential on each one can be made zero. Then select the correct relation.

$3 C_{1} + 5 C_{2} = 0$

$9 C_{1} = 4 C_{2}$

$5 C_{1} = 3 C_{2}$

$3 C_{1} = 5 C_{2}$

For potential to be made zero, after connection
$120C_{1} = 200C_{2}$
$\Rightarrow 3 C_{1} = 5 C_{2}$

Q. Two capacitors C1​ and C2​ are charged to 120 V and 200 V , respectively. It is observed that by connecting them together, the potential on each one can be made zero. Then select the correct relation.

3C1​+5C2​=0

9C1​=4C2​

5C1​=3C2​

3C1​=5C2​
