$27\mathrm{.}34-$ A straight, vertical wire carries a current of $2\mathrm{.}60$ A downward in a region between the poles of a large superconducting electromagnet, where the magnetic field has magnitude $B=0\mathrm{.}588T$ and is horizontal. What are the magnitude and direction of the magnetic force on a $1\mathrm{.}00$ cm section of the wire that is in this uniform magnetic field, if the magnetic field direction is $($a$)$ east; $($b$)$ south; $($c$)30\mathrm{.}0$ south of west?
