To find the net force acting on the object, we need to consider the directions of the forces along with their magnitudes.
- The first force is 30 N directed west.
- The second force is 12 N directed east.
Since west and east are in opposite directions, we can subtract the magnitudes of the forces to find the net force:
\[ \text{Net Force} = 30 , \text{N (west)} - 12 , \text{N (east)} = 30 , \text{N} - 12 , \text{N} = 18 , \text{N (west)} \]
Thus, the net force on the object is 18 N west.
