A dielectric slab is slowly inserted between the paltes of aparallel-plate capactiro, while the potential difference is heldconstant by a battery. As it is being inserted:
A. the capacitance, the potential difference between the plates,and the charge on the positve plate all increase
B.the capacitance, the potential difference between the plates, thecharge on the postive palte decrease, and the capactiance remainsthe same.
C. the potential difference between the plate increases, the chargeon the positve palte decreases, and capacitance remains thesame
D. The capacitance and the charge on the positive plate decreasebut the potential difference between the plates remain thesame,
E. the capacitance and the charge on the postive palte increase butthe potential difference between the paltes remain the same
