    attached is the question. i can't seem to figure out initial and boundary conditions. here is what i have so far:

    V(x, 0) = V_o - (V_o/d)x
    V(d, t) = 0
    V(0, t) = -V_o

    however, i don't think they're correct. can anyone help?

    (for those who have no knowledge of electricity, we assume that "earth" has 0 voltage relatively)

    I don't think that counter is correct since I looked at it a while back.

    My only comment is regarding "V(0, t) = -V_o"

    If t is >= 0 then surely "V(0, t) = 0" as it's just been connected directly to earth.

    but to bring the voltage from V_0 to 0 at that point, don't you need a step of height -V_0?

    No. Stating the obvious, but if you want the voltage to be 0 at that point, then you need the voltage to be 0 at that point.
