Three forces A, B, and C act on a body as shown. A fourth force F is required to keep the body in equilibrium.
-In the figure,the y-component of force F is closest to:

B)+28 N 
C)+32 N 
D)-28 N 
E)-32 N

Quizplus · Accepted Answer

The y-component of force F is equal to the sum of the y-components of the two forces acting on the object. The y-component of the force F1 is +24 N, and the y-component of the force F2 is +8 N. Therefore, the y-component of force F is +24 N + +8 N = +32 N.
