A charged particle is on an x-y plane. The particle starts from the origin, and begins by moving 14.0 centimeters, at an angle of 21.1o below the positive x-axis. The particle then changes direction and travels 11.1 cm at an angle of 38.8o above the positive x-axis. What is the particle’s displacement vector after these two motions? 17.7 cm, 6.71o above the positive x-axis 21.8 cm, 5.03o below the positive x-axis 21.8 cm, 5.03o above the positive x-axis 17.7 cm, 6.71o below the positive x-axis
