Two parallel-plate capacitors with diffe...

Two parallel-plate capacitors with different distances between the plates are connected in parallel to a voltago source. A point positive charge is moved from a point 1 that is exactly in the middle between the plates of a capacitor `Cl` to a point `2` (or a capacitor `C2`) that lies at a distance from the negative plate of `C2` equal to half the distance between the plates of `Cl.` Is any work done in the process?

A

positive

B

negative

C

zero

D

data insufficient.
