is R is the resultant of the tour forces A, B. C. and D. Find the magnitude of the angle 6 and the magnitude of C. A= 2200 N R= FBDD'N' 2. Particle A lies on the xy plane and is acted on by the three forces shown. Find the resultant of the three forces. Also find the direction cosines of the resultant. l" z . 3.
