Two capacitors `C_1` and `C_2` are charged to 120V and 200V respectively. It is found that connecting them together the potential on each one can be made zero. Then

Options

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

Answer

B

Explanation

On connecting the two charged capacitors, potential on each can be made zero only when their charges are equal and opposite, i.e., `q_(1) = q_(2)`
`120 C_(1) = 200 C_(2)`
`3 C_(1) = 5 C_(2)`
Choice (b) is correct.
