Question

Three forces F1, F2, and F3, act on an object simultaneously. These force vectors are shown in the following
free-body diagram. In which direction does the object accelerate? [Length of vector = magnitude of force)​

Answer 1

Answer:

F1 + F2 + F3 = 0

F2 + F3 = (-)F1

If   F1 force is reversed in direction ,

F2 + F3 - F1 = ma

-F1 -F1 = ma

-2F1 = ma

F1 = (ma)/2

Explanation:

Answer 2

Answer:In 3rd Quadrant

Explanation: As length depicts magnitude of vectors

Hence we can observe that F³ is largest in magnitude and F² is smallest. But F¹ makes the resultant force towards F². Hence the resultant force should be in 3rd quadrant.
