A small but rigid $-$shaped wire carrying a $5\mathrm{.}0-$AA current $($Figure $1)$ is placed inside a solenoid. The solenoid is $20$ cmcm long and has $600$ loops of wire, and the current in each loop is $7\mathrm{.}0$AA$.$ Part B

So the only force is on the left branch, which is defined to be of length ll$.$What is the net force per unit length on the $-$shaped wire?
