May i know how to solve this question?
and how do i solve it when the arrow on the left hand side of the diagram changes to the other direction?
, where .
Since the curve is closed, the conservative part can be dropped from the line integral: you only need to integrate along that curve.
Are you asking what happens if you reverse the direction of the entire curve? - Well, in that case the line integral changes its sign.and how do i solve it when the arrow on the left hand side of the diagram changes to the other direction?
sorry im still very confused how to solve this current question.
and for the question where if the direction on the left hand side changes, i was thinking that since both the arrows will now oppose each other, they will cancel out and hence the line integral will be 0? but i guess i cant say it that way right?
