Force between Current Carrying Wires: More Changes

APPHEM-JFKBS5

Two long straight parallel wires are attracted by a magnetic force $F$.

The current in the first wire is doubled.
The current in the second wire is tripled.
The separation of the wires is increased by a factor of $6$.

In terms of the original magnetic force $F$, what will the new magnetic force be?

A

$F$

B

$36F$

C

$\frac{1}{36}F$

D

$6F$

E

$\frac{1}{6}F$
