Concept:

We need to recall the concept of curl of  a vector field to answer this question.

Curl of a vector field F(x,y,z) = Xi+Yj+Zk is denoted by curl F.

Defined as: curl F =     \begin{vmatrix} i & j & k\\  \frac{d}{dx} &  \frac{d}{dy}&\frac{d}{dz} \\ X &Y  &Z \end{vmatrix}

Given:

The vector field F = xy i +xyz j +zy k

To find:

The curl of vector field at point (0,1,2).

Solution:

On Comparing the given vector field with

   F(x,y,z) = Xi+Yj+Zk

we get, X = xy

             Y = xyz

             Z = zy

Curl of F is given by :

Curl F =  \begin{vmatrix} i & j & k\\  \frac{d}{dx} &  \frac{d}{dy}&\frac{d}{dz} \\xy&xyz&zy\end{vmatrix}

          = (z-xy) i - (0-0) j + (yz- x) k

          =  (z-xy) i + 0 j + (yz- x) k

At point (0,1,2),

Curl F = (2-0×1 ) i +0 j + (1×2 -0) k

          = 2 i +0 j + 2k

Hence, curl of the vector field at point (0,1,2) is given  by : 2 i +0 j + 2k
