Final answer:
To achieve a net force of 0 N, forces must be equal in magnitude but opposite in direction. With a friction force of 5.00 N, any force equal and opposite to this value would lead to a net force of 0 N. Therefore, all options A) 5 N, -5 N, B) 10 N, -10 N, C) 15 N, -15 N, and D) 20 N, -20 N satisfy the condition.
Step-by-step explanation:
The question asks to find the missing forces such that the net force (Fnet) equals 0 N. To achieve a net force of 0 N, the forces must be equal in magnitude but opposite in direction. This means if one force is positive, the other must be negative and of the same magnitude to cancel each other out.
Given that the opposing friction force averages 5.00 N, we need a force that is equal in magnitude but opposite in direction to achieve Fnet = 0 N. Therefore, for each option:
- A) 5 N is opposed by -5 N.
- B) 10 N is opposed by -10 N.
- C) 15 N is opposed by -15 N.
- D) 20 N is opposed by -20 N.
All these options adhere to the requirement for Fnet to equal 0 N because the pairs of forces listed in each option are equal and opposite.
