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)
" O 42N west
• 18N east
• 18N west
• 42 N east
To find the net force on the object, we need to subtract the force directed east from the force directed west.
Magnitude of the force directed west = 30 N
Magnitude of the force directed east = 12 N
Net force = Force directed west - Force directed east
Net force = 30 N - 12 N = 18 N directed west
Therefore, the net force on the object is 18 N west, which is option C.
To find the net force on the object, we need to subtract the forces acting in opposite directions.
The force directed west has a magnitude of 30 N.
The force directed east has a magnitude of 12 N.
To find the net force, we subtract the smaller force from the larger force since they are acting in opposite directions.
30 N - 12 N = 18 N
Therefore, the net force on the object is 18 N directed west.
So the correct answer is:
• 18N west.
To find the net force on the object, we need to add up the forces acting on it. Since one force is directed west and the other is directed east, we need to consider their directions as well as their magnitudes.
The force of 30N directed west can be represented as -30N (since it's in the opposite direction to the positive west). The force of 12N directed east can be represented as +12N (since it's in the positive east direction).
Now, to find the net force, we simply need to add these two forces together:
-30N + 12N = -18N
Therefore, the net force on the object is 18N, directed in the west direction. Hence, the correct answer is "• 18N west".
