Solve the all parts of following problem:

Problem: Two parallel wires separated by 4.2 cm repel each other with a force per unit length of 1.9 x 10^-4 Nm. The current in one wire is 4.9 A.

Part A: Find the current in the other wire.

Part B: Are the currents in the same direction or in opposite directions?

Part C: What would happen if the direction of one current were reversed and doubled?

I would really appreciate some help for above problem.
