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

A. 42 N east
B. 18 N east
C. 18 N west
D. 42 N west

To find the net force, we need to add the two forces together.

Since one force is directed west (to the left) and the other force is directed east (to the right), we need to subtract the force directed west from the force directed east.

12 N - 30 N = -18 N

Therefore, the net force on the object is 18 N west.

The correct answer is C. 18 N west.
