Question

8.
net force:
forces are: balanced unbalanced
object will:

Explanation:

Assume the two 5N forces are opposite, and the two 7N forces are opposite (common in such diagrams).

Step1: Calculate net force for 5N pair

$F_{net1} = 5N - 5N = 0N$

Step2: Calculate net force for 7N pair

$F_{net2} = 7N - 7N = 0N$

Step3: Total net force

$F_{total} = F_{net1} + F_{net2} = 0N$

Answer:

Net force: 0N
Forces are: balanced
Object will: not change its motion (remain at rest or constant velocity)
