Let

\vec{v} = (12; 5)

. Find all the vectors

\vec{u}

that are perpendicular to the vector

\vec{v}

and have the length of

26

.

\vec{u_{1}} = (10; - 24); \vec{u_{2}} = (- 10; 24)

\vec{u} = (10; - 24)

\vec{u_{1}} = \frac{1}{2} (5; - 12); \vec{u_{2}} = \frac{1}{2} (- 5; 12)

\vec{u_{1}} = 26 \cdot (5; - 12); \vec{u_{2}} = 26 \cdot (- 5; 12)
