문제 5

To open a door, you exert a force at a point with a position vector r=2i^3j^\(\vec{r}\)=2\(\text{m }\[\hat{i}\)-3\(\text{m }\]\hat{j}\) with respect to the hinge. The exerted force is given in unit-vector notation as F=15i^10j^\(\vec{F}\)=15\(\text{N }\[\hat{i}\)-10\(\text{N }\]\hat{j}\). The hinge is located at the origin of the Cartesian plane. In a graphic, draw the position vector r\(\vec{r}\) and the force F\(\vec{F}\).
