Two very long straight wires P and Q carry currents of `10A` and `20A` respectively, and are at a distance `20cm` apart. If a third wire R (length `15cm`) having a current of `10A` is placed in middle between them, how much force will act on R? The direction of current in all the three wires is the same.

Two very long, straight parallel wires P and Q carry currents 5A and 10A respectively and are at a distance of 10cm apart, as shown in figure. If a third wire R (length 10cm ) having a current of 5A is placed in middle between them, how much force will be acting on R? The direction of current in all the wires is the same.
