Locations $A,B,$ and $C$ are in a region of uniform electric field, as shown in the diagram above. Location $A$ is at Location $B$ is at $($:$0\mathrm{.}5,0,0$:$)m.$ In the region the electric field vec$(E)=($:$850,0,0$:$)\frac{N}{C}.$

For a path starting at $B$ and ending at $A,$ calculate the following quantities:
