2.3.8 Forces and Newton's laws

Question 2

A particle is moving across a perfectly smooth horizontal surface at a constant velocity. It is acted upon by exactly two constant horizontal forces.

The first force is $N\mathbf{F}_1 = (250\mathbf{i} - 120\mathbf{j})\text{ N}$ .

The second force is $N\mathbf{F}_2 = (k\mathbf{i} + 120\mathbf{j})\text{ N}$ .

Find the value of $k$ .
