Question

Sketch the vector field F
F(x,y,z)=j-i
Please give me a second to draw it.

Answer 1

I'm not sure anymore. Is the i vector drawn parallel to the x axis in the negative direction of x?

Answer 2

Like so?

Answer 3

yes, because the the - sign.

Answer 4

do the arrows tilt a certain way because j is postive?

Answer 5

yes. you have to add the j component to the -i vector. best to do this in the xy-plane, since this field had no k component

Answer 6

Good idea.

Answer 7

and since the field has no dependance on x or y, the field is constant everywhere.
