Capacitor Parallel Charge Transfer
Parallel Plate Capacitor
A Parallel Plate Capacitor consists of two large, flat, conductive plates. Each plate has an area (A), and they are separated by a distance (d). When we charge the plates, one holds a positive charge (+Q) and the other an equal negative charge (-Q).
8.4: Energy Stored in a Capacitor
Knowing that the energy stored in a capacitor is (U_C = Q^2/(2C)), we can now find the energy density (u_E) stored in a vacuum between the plates of a charged parallel-plate capacitor. We just have to divide (U_C) by the volume Ad of space between its plates and take into account that for a parallel-plate capacitor, we have (E = sigma/epsilon_0) …

Derivation of Capacitance Formula for a Parallel Plate Capacitor Strategy: To deduce the formula given in, we find the potential difference (V) when plates are charged (pm Q) and then get capacitance from (V/Qtext{.}) Assuming plates to be infinitely large with ...
Capacitors | Brilliant Math & Science Wiki
4 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity …

Your answer is wrong in the sense that the charge will not be equally divided between the plates of the two capacitors. And the reason is that the capacitors have different capacitances. In this case you need to apply Kirchoff''s voltage rule to get the correct equation.

Electric field in a parallel plate capacitor
During the charge of a capacitor, a positive charge dq is transferred from the negative plate to the positive one. But, in order to do that, it is necessary to provide a certain amount of energy in the form of work, because if it were not the case, the positive charge would be repelled by the negative plate.
