The figure shows capacitor $1($C$\_(1)=6\mathrm{.}21\backslash$mu $($F$)),$ capacitor $2($C$\_(2)=7\mathrm{.}92\backslash$mu $($F$)),$ and capacitor $3($C$\_(3)=8\mathrm{.}14\backslash$mu $($F$))$ connected to a $13\mathrm{.}7$ V battery.

When switch S is closed so as to connect uncharged capacitor $4($C$\_(4)=7\mathrm{.}45\backslash$mu $($F$))$a P from the

battery and $($b$)$ how much charge shows up on capa$-$: $^(---1)$
