1. Two forces are applied to the ring of a force table, one at an angle of 95°, and the other at an angle of
170°. Regardless of the magnitudes of the forces, the equilibrant will be in the
(a) first quadrant
(b) second quadrant
(c) third quadrant
(d) fourth quadrant
(e) Cannot tell which quadrant from the available information.
2. Two forces, one of magnitude 9N and the other of magnitude 4N, are applied to the ring of a force table.
The directions of both forces are unknown. Which best describes the limitations on R, the resultant?
(a) R< 13N
(b) 4N < R < 9N
(c) R >13 N
(d) 5N < R < 13N
(e) R < 4N.
