As Shown in the Figure, Three Force Vectors Act on an Object

Multiple Choice

As shown in the figure, three force vectors act on an object. The magnitudes of the forces as shown in the figure are = 80.0 N,
= 60.0 N, and
= 40.0 N, where N is the standard SI unit of force. The resultant force acting on the object is given by

A) 180 N at an angle 60.0° with respect to +x-axis.
B) 60.0 N at an angle 90.0° with respect to +x-axis.
C) 20.0 N at an angle 34.3° with respect to +x-axis.
D) 35.5 N at an angle 34.3° with respect to +x-axis.
E) 40.0 N at an angle 60.0° with respect to +x-axis.
