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) Responses 42N west 42N west 42 N east 42 N east 18N east 18N east 18N west 18N west
The net force on the object is 18N west.
To find the net force on the object, we need to subtract the smaller force from the larger force and determine the direction of the resultant force.
Magnitude of the larger force = 30 N (west)
Magnitude of the smaller force = 12 N (east)
Since the forces are in opposite directions, we can subtract their magnitudes to find the net force:
Net force = 30 N - 12 N
Subtracting the magnitudes:
30 N - 12 N = 18 N
The net force on the object is 18 N. Since the larger force is directed west, the net force will also be directed in that direction.
The correct response is: 18N west.
To find the net force acting on the object, we need to determine the sum of the two forces. Since one force is directed west and the other force is directed east, they are acting in opposite directions. Therefore, we can subtract the magnitude of the eastward force from the magnitude of the westward force.
Magnitude of westward force = 30 N
Magnitude of eastward force = 12 N
Net force = Magnitude of westward force - Magnitude of eastward force
Net force = 30 N - 12 N
Net force = 18 N
Therefore, the net force on the object is 18 N. However, we also need to consider the direction of the net force. Since the westward force is greater, the net force is in the direction of the greater force, which is west.
Hence, the correct response is 18N west.
