The net force on the object is 18N west.
To find the net force on an object, we need to add the two forces together. Since one force is directed west and the other is directed east, we need to consider their directions as well.
The force of 30N directed west can be represented as -30N (negative because it is in the opposite direction of positive west).
The force of 12N directed east can be represented as +12N (positive because it is in the same direction as positive east).
Adding these forces together, we have:
-30N + 12N = -18N
The net force on the object is -18N, which means it is 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 individual forces acting on it.
In this case, you have two forces: one with a magnitude of 30N directed west and the other with a magnitude of 12N directed east.
To calculate the net force, you need to add the magnitudes of these forces and consider their directions.
Since the force directed west has a magnitude of 30N, and the force directed east has a magnitude of 12N, the net force is the difference between the two magnitudes:
30N - 12N = 18N west
Therefore, the correct answer is 18N west.
