Question

what is the net force? 4 n → □ ← 5 n
a 5 - 4 = 1n to the right
b 5 - 4 = 1n to the left
c 4 + 5 = 9n to the left
d 4 + 5 = 9n to the right

Explanation:

Step1: Analyze Force Directions

Forces are in opposite directions (right: 4N, left: 5N). Net force for opposite forces is the difference of magnitudes.

Step2: Calculate Net Force Magnitude

Subtract smaller force from larger: \( 5 - 4 = 1 \, \text{N} \).

Step3: Determine Direction

Larger force (5N) is to the left, so net force direction is left.

Answer:

B. \( 5 - 4 = 1\text{N} \) to the left
