Charge in a circuit

Electricity and Magnetism Level 2

In the given circuit, a charge of $+80 µC$ is given to the upper plate of the $4 µF$ capacitor. Then in the steady state, the charge on the upper plate of the $3 µF$ capacitor is

+32 µC

+48 µC

+80 µC

+40 µC

2x +3x =80 => x=16 (V at junction) hence Q on 3uF capacitor equals 3x=48uC.

why you have assumed that there is no charge will be stored in 4uf capacitor if there is no obligation the 4uf capacitor will store charge comparable to 5uf cap. (3uf and 2uf cap.in parallel) are you sure of your answer??
