Answer 2

that's 400, but that doesn't work.

Answer 4

I think the way to approach this is to understand that potential difference can be written as:\[V_{f}-V_{i}=-\int \vec{E} \cdot d\vec{s}\]

An integral can be interpreted as an area under a curve. That should lead you in the right direction.

Answer 5

i tried that and it didn't work either. i have 1 attempt left.
