In x-y plane, there exist 2 circles  $C_1:{(x-1)}^2+{(y-2)}^2=4$ and $C_2:{(x-5)}^2+{(y-2)}^2=4$ . In the region, there exist two variable forces given by:
${\overline{F}}_1=k\{(1-y)\widehat{i}+(x-2)\widehat{j}\}$  and  ${\overline{F}}_2=\frac{k\{(1-y)\widehat{i}+(x-2)\widehat{j}\}}{{(1-y)}^2+{(x-2)}^2}$
Let  $W_{ij}$  represent the work done by ${\overline{F}}_i$   in a complete rotation in anticlockwise direction for cyclic path along circle $C_j$ . Match  $W_{ij}$  in Column-I to its value in Column-II.
