Problem

Two capacitors

A

and

B

are connected in series across a

100\text{ V}

supply. The potential differences across them are

60\text{ V}

and

40\text{ V}

, respectively. A capacitor of capacitance

2\,\mu\mathrm{F}

is connected in parallel with

A

, and the potential difference across

B

rises to

90\text{ V}

. Determine the capacitances of

A

and

B
