Two long straight wires P and Q carrying equal current 10A each were kept parallel to each other at 5 cm distance. Magnitude of magnetic force experienced by 10 cm length of wire P is F 1 . If distance between wires is halved and currents on them are doubled, force F 2 on 10 cm length of wire P will be:
