Homework Equations





The Attempt at a Solution



I'm having some confusion about the negative sign within this problem.

If you compute the curl of the expression shown in the figure you'll find that it's equal to,

[tex]-10v_{0} \hat{k}[/tex]

But if we take the direction of the normal of the surface to be

[tex]-\hat{k}[/tex]

so it points in the same direction that negative sign in his solution should go away, correct?

In the problem they tell you the line integral is in the counter-clockwise direction, the minus sign just means the current flows clockwise.

Hope this helps.

Sorry I misunderstood your comment.

This is more clear now.
