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)
A. 42N west
B. 42 N east
C. 18N west
D. 18N east
To determine the net force on the object, we subtract the force directed east from the force directed west.
30 N west - 12 N east = 18 N west
Therefore, the net force on the object is 18 N west.
The correct answer is C. 18 N west.
To find the net force on the object, we need to consider the direction and magnitude of each force.
The force directed west has a magnitude of 30N, while the force directed east has a magnitude of 12N.
To find the net force, we can subtract the magnitude of the force directed east from the magnitude of the force directed west:
30N - 12N = 18N
Since the force directed west has a greater magnitude, the net force on the object is 18N west.
Therefore, the answer is C. 18N west.
To find the net force on an object, you need to add the individual forces acting on it. In this case, one force has a magnitude of 30 N directed west, and the other force has a magnitude of 12 N directed east.
To add these forces, you can simply subtract the force directed east from the force directed west because they have opposite directions.
30 N (west) - 12 N (east) = 18 N (west)
So, the net force on the object is 18 N directed west.
Therefore, the correct answer is C. 18N west.
