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)
18N west
42 N east
42N west
18N east
The net force on the object is the vector sum of the two forces. Since one force is directed west and has a magnitude of 30N, and the other force is directed east and has a magnitude of 12N, we can calculate the net force by subtracting the smaller force (12N) from the larger force (30N) and taking into account their directions.
30N west - 12N east = 18N west
The net force on the object is 18N west.
So, the correct answer is 18N west.
