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