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.  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/PR_XII_V01_C03_E01_154_Q01.png" width="80%"
