Two long straight wires P and Q carrying equal current $\displaystyle 10$ A each were kept parallel to each other at $\displaystyle 5$ cm distance. Magnitude of magnetic force experienced by $\displaystyle 10$ cm length of wire P is $\displaystyle \mathrm{F}_1$. If distance between wires is halved and currents on them are doubled, force $\displaystyle F_2$ on $\displaystyle 10$ cm length of wire P will be:
