Current Attempt in Progress

In the figure a potential difference $V=150V$ is applied across a capacitor arrangement with capacitances $C_1=13\mathrm{.}8F,C_2=3\mathrm{.}78F,$ and $C_3=4\mathrm{.}62F.$ What are $($a$)$ charge $q_3,($b$)$ potential difference $V_3,$ and $($c$)$ stored energy $U_3$ for capacitor $3,($d$)q_1,(e)V_1,$ and $(f)U_1$ for capacitor $1,$ and $(g)q_2($ h
