The voltage required is 11 V.

First calculate the total capacitance of each combination.

**Series**:

(Note that I did not convert the

**Parallel**:

Next calculate the energy stored in the series arrangement:

Now calculate the voltage that would give the parallel combination the same total energy stored (
