The resultant force range of 6N and 9N

15N
When the two forces are in the opposite direction, they are the minimum, and the resultant force is subtracted
When the two forces are in the same direction, the resultant force is the largest and the two forces are added together

The magnitude of three forces acting on an object is 7n, 8N and 9N respectively, and the resultant force may be ()
A. 0B. 7NC. 15ND. 25N

According to the theme, when three forces act on an object in the same direction, the resultant force is the largest, the maximum is Fmax = 7n + 8N + 9N = 24N; the resultant force of 7n and 8N ranges from 1n to 15N, then 9N can be balanced with the resultant force of 7n and 8N, so the resultant force of three forces can be zero, so the resultant force of three forces ranges from 0 ≤ f ≤ 24N, so ABC is correct, D is wrong ：ABC．
