Question 1 of 15

If a vector field $\vec V$is related to another vector field $\vec A$through $\vec V$= $\nabla$x $\vec A$, which of the following is true? (Note : C and S_c refer to any closed contour and any surface whose boundary is C.)

Select Your Answer:

$\oint_0 \vec V. \vec{dl} = \int_z \int \vec A. \vec d S$

$\oint_0 \vec A. \vec{dl} = \int_z \int \vec V. \vec d S$

$\oint_0 \vec V. \vec{dl} = \int_z \int \Delta x \vec A. \vec d S$

$\oint_0 \Delta x \vec V. \vec{dl} = \int_z \int \vec V. \vec d S$
