Given two forces and acting on an object, F1=-2i+3j and F2= 7i-4j (i) obtain the third force so that the object stays in translational equilibrium, (ii) find its magnitude and direction (with respect to horizontal axis +x)? (i, and j represent unit vectors in x, and y directions, respectively.)

  • after F2=7i-4j it should say acting on an object Jason commented about 1 year ago

Both forces have vectors in the same directions, i and j. Therefore, to reach equilibrium the third force has to cancel those vectors out. F1-F2=5i-j, so F3=-5i+j.
