need help with solution

A circuit contains a switch and two capacitors connected in parallel as shown in the picture. Before the switch is closed, there is a potential difference of 10 volts across capacitor C1 = 1.6 F and 0 volts across capacitor C2 = 1.3 F. After the switch is closed and C, shares its charge with C2, what potential difference (in Volts) will the voltmeter read on either capacitor? You answer should be of one decimal place
