voltage/ electric field question

[donjt81]

Consider a uniform electric field of 50 N/C directed toward the east. If the voltage measured relative to ground at a given point in the field is 80V, what is the voltage at a point 1.0 m directly south of that point?

any pointers on how to do this?

Hint: if it's a uniform electric field pointing to the east, does it vary in the north-south direction?

ohhh ok... so that makes sense. it wont change going N and S.

Ok so is they asked in the test... same question but this time "what is the voltage at a point 1.0 m directly east of the point?"

An electric field of 50 N/C can also be expressed as 50 V/m.
