81. Two large parallel plates a distance d apart are charged by connecting them to a battery of potential difference V. The battery is disconnected, and the plates are slowly moved apart. As the distance between plates increases:
(A) the charge on the plates decreases.
(B) the electric field intensity between the plates increases.
(C) the potential difference between the plates decreases.
(D) the potential difference between the plates increases.
(A) the charge on the plates decreases.
(B) the electric field intensity between the plates increases.
(C) the potential difference between the plates decreases.
(D) the potential difference between the plates increases.
