Two forces of magnitude F have a resultant of the same magnitude F. The angle between the two forces is
(1) 45°
(2) 120°
(3) 150°
(4) 60°
Two forces with equal magnitudes F act on a body and the magnitude of the resultant force is F/3. The angle between the two forces is

(2)
(3)
(4)
Two forces are such that the sum of their magnitudes is 18 N and their resultant is perpendicular to the smaller force and the magnitude of the resultant is 12 N. Then the magnitudes of the forces will be:
1. 12 N, 6 N
2. 13 N, 5N
3. 10 N, 8 N
4. 16 N, 2 N
If two forces of 5 N each are acting along X and Y axes, then the magnitude and direction of resultant is
