Charge Q will be same on both the capacitors that are in series.

For capacitor A

Q = C1(40V )

For capacitor B

Q = C2(60V)

So C1/C2 = 3/2

C1 = 3x and C2 = 2x

On connecting 6 microfarad with B the potential drop is equal to that across A, so the capacitance of this combination is equal to the capacitance of A.

Now you can write an equation in variable x and solve it to find C1 and C2.

A parallel-plate capacitor has a plate area of 100c * m ^ 2 and a plate separation of 2.0 cm. has been charged up to 3000 V by a battery. Now, (i) after disconnecting the battery, (ii) keeping the battery connected, the distance between the plates is increased to 5.0 cm intensity of electric field between the plates and the energy of the capacitor. ( epsilon_{0} = 8.85 * 10 ^ - 12 * F * m ^ - 1
