Die grootte van Rx is 7,4 N so die pyl wat ons moet teken moet 7,4 cm lank wees. Die<br />

Rx<br />

Die grootte van Ry is 3 N, so die pyl wat ons moet teken moet 3 cm lank wees. Die<br />

pyl moet in die negatiewe y-rigting wys. Dit is belangrik om daarop te let dat ons die<br />

stert-tot-kop metode gebruik, so die vektor moet begin by die einde (kop) van Rx.<br />
