A high-precision maglev puck is gliding across a frictionless experimental surface at a constant velocity. It is subject to exactly two constant horizontal magnetic forces, F1\mathbf{F}_1F1​ and F2\mathbf{F}_2F2​.

The first force is F1=(105.4i−62.75j) N\mathbf{F}_1 = (105.4\mathbf{i} - 62.75\mathbf{j})\text{ N}F1​=(105.4i−62.75j) N.

The second force is F2=(ki+62.75j) N\mathbf{F}_2 = (k\mathbf{i} + 62.75\mathbf{j})\text{ N}F2​=(ki+62.75j) N.

Determine the value of kkk.

Select your answer from the following:

-105.4

-62.75

62.75
