In the question number 66, the charge on capacitors C_(1)and C_(4) are

Answer»

`4xx10^(-3)C, 12xx10^(-3)C`
`6xx10^(-3)C,12xx10^(-3)C`
`2xx10^(-3)C,4xx10^(-3)C`
`3xx10^(-3)C, 2xx10^(-3)C`

Solution : Chargeon eachcapacitor `C_(1),C_(2),C_(3)` is same = q Letcharge on `C_(4)` be q.
`therefore(q)/(C_(1)) + (q)/(C_(2)) + (q)/(C_(3)) = 600`
`or q [(1)/(C_(1)) + (1)/(C_(2)) +(1)/(C_(3)) ] = 600`
`or(q)/(C_(s)) = 600`
`therefore "" q = 600 C_(s) = 60 xx (20)/(3) mu C = 4000 xx 10^(-6) C = 4 xx 10^(-3) C`
Also `(q)/(C_(4)) = 600`
or `q = C_(4) xx 600 MUC= 20 xx 600 mu C = 12 xx 10^(-3)C`
