A capacitor 
with capacitance 
is fully charged with a potential difference of 6.0 V and disconnected from the battery. The charged capacitor 
is connected across another capacitor 
with capacitance 
. The charge on capacitor 
when equilibrium is established will be 
(assume capacitor 
does not have any charge initially), the value of 
is 
.

(4)
Capacitor 
is charged to 6.0 V.
Initial charge: 
.
When connected to uncharged capacitor 
, charge redistributes until both reach same potential.
Final voltage: 
.
Charge on Q: 
.
Thus 
.
