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

For potential to be made zero after connection, the charge both capacitors are equal
`therefore q_(1)=q_(2)`
`implies C_(1)V_(1)=C_(2)V_(2)`
`implies 120C_(1)=200C_(2) implies 3C_(1)=5C_(2)` .
