49. In the following diagram, which force could act concurrently with force A to produce force B as a resultant?
50. Three forces of 10. newtons, 8 newtons, and 6 newtons act concurrently on an object in equilibrium. The resultant of the 6-newton and 8-newton forces has a magnitude of (1) 0.0 N (2) between 0.0 N and 10.N (3) 10.N (4) more than 10.N
51. Into how many possible components can a single force be resolved? (1) an unlimited number (2) two components (3) three components (4) four components at right angles to each other
52. A lawnmower is pushed with a constant force F, as shown in the following diagram.
As angle θ between the lawnmower handle and the horizontal increases, the horizontal component of F (1) decreases (2) increases (3) remains the same
