In unit$-$ vector notation, what is the torque about the$$origin on a$$particle located at coordinates $(0,4\mathrm{.}0$ m$,3\mathrm{.}0$m$)$ if that torque is due to $($a$)$ forceF $1$with components$$F$1$x $=2\mathrm{.}0$N$,$ F$1$y $=$ F$1$z $=0,$ and $($b$)$ forceF $2$with components F$2$x $=0,$ F$2$y $=2\mathrm{.}0$ N$,$ F$2$z $=4\mathrm{.}0$ N$?$
