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?
42 N east
18n east
42N west
18Nwest
To find the net force on the object, we need to consider the direction of each force.
The force of 30 N directed west is in the opposite direction of the force of 12 N directed east.
Since they are in opposite directions, we need to subtract their magnitudes to find the net force.
|30 N| - |12 N| = 18 N
The net force on the object is 18 N.
However, since the original direction of the force with the larger magnitude (30 N) is west and the force with the smaller magnitude (12 N) is east, we need to consider their directions.
The net force is directed from west to east, so the final answer is 18 N east.
Therefore, the correct answer is 18 N east.
