Homework Equations


##V=Ed##
##ΔU=ΔV Q##

The Attempt at a Solution


Since the electric field is constant between charged plate conductors , d and the potential difference (ΔV) don't change.So, the potential energy (ΔU) remain the same .
The answer is (C). Right ?

The answer is (C). Right ?
How did you deduce this from the above?
