F1 = 6N, F2 = 8N, find the range of F3 force and the resultant force of F2 and F3

F1 = 6N, F2 = 8N, find the range of F3 force and the resultant force of F2 and F3


Range of F3 force: greater than or equal to 2n and less than or equal to 14N
The resultant force of F2 and F3 is 6N, opposite to F1
Your question is not complete, the resultant force of three forces is 0, or the three forces are static or uniform, otherwise you can't do it



The three forces in the same plane are F1 = 6N, F2 = 7n, F3 = 8N. The three forces act on the same object in different directions, and the object moves at a constant speed. If F3 is cancelled, then the resultant force of F1 and F2 on the object? The resultant force direction?


Because it is moving at a constant speed, the object is in a state of equilibrium. According to the force balance conditions, the resultant force of F1F2 is equal to F3, the resultant force of f3f1 is equal to F2, and the resultant force of f2f3 is equal to F1. This relationship always needs to be satisfied. Therefore, the resultant force of F1 and F2 is equal to F3. The resultant force of F1F2 and F3 can be regarded as two force balance. According to the two force balance conditions, its direction is opposite to F3



If there are three forces, F1 = 2n, F2 = 5N, F3 = 8N, then ()
A. F 1 may be the resultant force of F 2 and F 3 B. F 2 may be the resultant force of F 1 and F 3 C. f 3 may be the resultant force of F 1 and F 2 d


A. The resultant force range of F2 and F3 is 3N ≤ f ≤ 13N, F1 is not in this range, so F1 cannot be the resultant force of F2 and F3, so a error; the resultant force range of B, F1 and F3 is 6N ≤ f ≤ 10N, F2 is not in this range, so F2 cannot be the resultant force of F1 and F3, so B error; the resultant force range of C, F1 and F2
