The region between x = 0 and x = d is free space and has v = 0(x — d)/d. If V(x = 0) = 0 and V(x = d) = V0, find: (a) V and E, (b) the surface charge densities at x = 0 and x = d.

a and c

c is 100% but i am confused in a

its c i just checked it

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
