Answer:
Fc= 4x10^-5 N towards left
Explanation:
to explain this, first consider the attachments. It contains figure 1 and then the answer.
Answer explanation;
As seen in the picture, direction of current C and D are in opposite direction; so force of repulsion will act on C. Similarly due to G it will be on G it will be in left hand side, so resultant force on C due to wires D and G will be F.
Now the calculation can be seen in attached pdf file.
