Two forces act on an object. One force has a magnitude of 30N directed west, and the other force has a magnitude of 12 N directed east. What is the net force on the object?(1 point) Responses 18N east 18N east 18N west 18N west 42 N east 42 N east 42N west
The net force on the object is equal to the vector sum of the two forces. Since one force is directed west with a magnitude of 30N, and the other force is directed east with a magnitude of 12N, we can calculate the net force by subtracting the eastward force from the westward force:
30N west - 12N east = 18N west
Therefore, the net force on the object is 18N west.
To find the net force on the object, you need to calculate the resultant force by considering the magnitudes and directions of the two forces.
The force of 30N directed west and the force of 12N directed east can be added together to find the net force.
Since the forces are in opposite directions, you subtract the smaller force from the larger force and use the direction of the larger force. In this case, the force of 30N (west) is larger than the force of 12N (east).
So, the net force on the object is 30N - 12N = 18N directed west.
Therefore, the correct answer is: 18N west.
To find the net force on an object, you need to calculate the vector sum of the given forces. Since the forces are in opposite directions, you can subtract the magnitude of the force acting in one direction from the magnitude of the force acting in the other direction.
In this case, we have a force of 30N directed west and a force of 12N directed east. Since the force directed east is smaller, we subtract its magnitude from the force directed west:
30N - 12N = 18N west.
Therefore, the net force on the object is 18N west.
