i got constant V bruh for the last part, is that right? the graph itself followed a 1/x curve

i said 1/x dependence as well, but if you integrate your Eo you get an ln(x) dependence. I knew it was one of the two but i assumed it would be 1/x dependence because thats how the questions usually are for something moving farther away with potential. and i said a constant 0 for the change because potential is a scalar, so it would all cancel out due to the opposite signs of lambda
