While two forces act on it$,$ a particle is to move at the constant velocity vec$(v)=(3\mathrm{.}23\frac{m}{s})hat(i)-(-3\mathrm{.}03\frac{m}{s})hat(j).$One of the forces is vec$(F{)}_1=(1\mathrm{.}96N)hat(i)+(-6\mathrm{.}61N)hat(j).$ What is the other force?

Number $$

$$ hat$(i)+$ hat$(j)$ Units $$
