Question

1. which of the following represents unbalanced forces? directions: calculate the net f

Explanation:

Step1: Recall the concept of balanced and unbalanced forces

Balanced forces have a net - force of zero. Unbalanced forces have a non - zero net force.

Step2: Analyze the first option (7N and 3N in the same direction)

The net force $F_{net}=7N + 3N=10N
eq0$.

Step3: Analyze the second option (5N and 5N in opposite directions)

The net force $F_{net}=5N-5N = 0N$.

Step4: Analyze the third option (5N and 4N in opposite directions)

The net force $F_{net}=5N - 4N=1N
eq0$.

Step5: Analyze the fourth option (2N and 2N in opposite directions)

The net force $F_{net}=2N-2N = 0N$.

Answer:

The options with 7N and 3N in the same direction and 5N and 4N in opposite directions represent unbalanced forces.
