Potential difference across a capacitor

In figure 25-27 in attached file 5, a potential difference V= 100 V is applied across a capacitor arrangement with capacitance C1=10.0 uF, C2 = 5.00 uF and C3= 4.00 uF. What are (a) charge q3.
(b) the potential difference V3.
(c) stored energy U3 for capacitor 3.
(d) q1
(e) V1
(f) U1, all for capacitor 1
(g) q2
(h) V2
(i) U2, all for capacitor 2
