Two capacitors having capacitances `C_(1)` and `C_(2)` are charged with 120 V and 200 V batteries respectively. When they are connected in parallel now, it is found that the potential on each one of them is zero. Then,

Options

A. `5C_(1)=3C_(2)`
B. `3C_(1)=5C_(2)`
C. `3C_(1) pm 5C_(2)=0`
D. `9C_(1)=4C_(2)`

Answer

C

Explanation

Polarity should be mentioned in the question. Potential on each of them can be zero if, `q_("net")=0`.
`q_(1)pmq_(2)=0`
`rArr" "120C_(1)pm 200C_(2)=0`
`rArr" "3C_(1)pm5C_(2)=0`
