A particle is located at the vector position $=(8\mathrm{.}00+9\mathrm{.}00)$ m and a force exerted on it is given by $=(6\mathrm{.}00+5\mathrm{.}00)$ N$.$

$($a$)$ What is the torque acting on the particle about the origin?

$=$

$4$

N $$ m

$($b$)$ Can there be another point about which the torque caused by this force on this particle will be in the opposite direction and half as large in magnitude?

Yes
