Two wires are carrying the same current in the same direction and feel an attractive force $F.$ If the current in each of these is increased by a factor of $3\mathrm{.}00$ and the distance between them is increased by a factor of $4\mathrm{.}00,$ the force becomes

$1\mathrm{.}13F$

$4\mathrm{.}50F$

$6\mathrm{.}75F$

$2\mathrm{.}25F$
