A plum is located at coordinates

$(3\mathrm{.}0$ m$,0\mathrm{.}0$ m$,3\mathrm{.}0$ m$).$

In unit$-$vector notation, what is the torque about the origin on the plum due to force whose only component is indicated by each of the following equations?

$($a$)$

Fx $=8\mathrm{.}0$ N

$$

$=$

N $$ m

$($b$)$

Fx $=2\mathrm{.}0$ N

$$

$=$

N $$ m

$($c$)$

Fz $=7\mathrm{.}0$ N

$$

$=$

N $$ m

$($d$)$

Fz $=9\mathrm{.}0$ N

$$

$=$

N $$ m
