Question
A student drew a force diagram for walking their dog and arrow pointing from left to right shows the student pulling on the leash with a force of 20 N an arrow from right to left shows the dog pulling on the leash in the opposite direction with a force of 10 n what is the net force and direction A 5 N total the right B 10 N to the left C 10 N to the right D 0 N the dog does not move

To find the net force, we need to consider the forces acting on the system:
1. The student pulls on the leash with a force of 20 N to the right.
2. The dog pulls on the leash with a force of 10 N to the left.
To calculate the net force, we subtract the smaller force (the dog's pull) from the larger force (the student's pull):
\[
\text{Net Force} = \text{Force by Student} - \text{Force by Dog}
\]
\[
\text{Net Force} = 20 \, \text{N (right)} - 10 \, \text{N (left)}
\]
Since we consider the right direction positive:
\[
\text{Net Force} = 20 \, \text{N} - 10 \, \text{N} = 10 \, \text{N \, (to the right)}
\]
Therefore, the net force is **10 N to the right**.
The correct answer is **C) 10 N to the right**.
1. The student pulls on the leash with a force of 20 N to the right.
2. The dog pulls on the leash with a force of 10 N to the left.
To calculate the net force, we subtract the smaller force (the dog's pull) from the larger force (the student's pull):
\[
\text{Net Force} = \text{Force by Student} - \text{Force by Dog}
\]
\[
\text{Net Force} = 20 \, \text{N (right)} - 10 \, \text{N (left)}
\]
Since we consider the right direction positive:
\[
\text{Net Force} = 20 \, \text{N} - 10 \, \text{N} = 10 \, \text{N \, (to the right)}
\]
Therefore, the net force is **10 N to the right**.
The correct answer is **C) 10 N to the right**.
