Explanation / Answer

If two vectors point along the same 'general direction', their dot product is positive.

First one is 0 as the negative on the x and positive on the y cancel out

Second is 0 as the curve is perpendicular to the vector field at all points

Third is positive as the curve is at right angle on the right half and makes an acute angle on the left half .

Fourth is 0 as the curve is symmetric and the positive cancels out the negative

Fifth is positive as the dot product of hypotenus with field is positive and the remaining 2 are 0

Sixth is positive as the larger circle is in the direction of the field and smaller is against it
