Two parallel-plate capacitors with different distances between the plates are connected in parallel to a voltage source. A point positive charge is moved from a point `A`, that is exactly in the middle between the plates of a capacitor `C_(1)` to a point `B`(or a capacitor `C_(2)` that lies at a distance from the negative plate of `C_(2)` equal to half the distance between the plates of `C_(1)`) During this process of moving the charge.
.

Answer

Work done by the field `=Q(V_(1)-V_(2))`
