Find the equivalent capacitance between points a and b for

the group of capacitors connected$($a$)$ Find the equivalent capacitance between points a and $b$ for

the group of capacitors connected as shown in Figure. Take

$C_1=5\mathrm{.}00F,C_2=10\mathrm{.}0F,$ and $C_3=2\mathrm{.}00F.$

$($b$)$ What charge is stored on $C_3$ if the potential difference

between points a and $b$ is $60\mathrm{.}0V?$
