To find the resultant of two forces acting at a point, you need to use vector addition. The resultant force is determined by adding the individual forces together.
If two forces, one with a magnitude of 5N and the other with a magnitude of 12N, act at a point, you can find the resultant force by adding these two forces as vectors. The magnitude of the resultant force will depend on the direction and angle between the two forces.
To calculate the resultant force, you need to use the vector addition formula, which takes into account both magnitude and direction. Since we don't have information about the angle or direction of the forces, we cannot determine the exact magnitude and direction of the resultant force.
However, we can calculate the maximum and minimum magnitudes of the resultant force. In this case, the maximum magnitude would occur when the two forces are aligned in the same direction, and the minimum magnitude would occur when the two forces are aligned in opposite directions.
Using the maximum magnitude:
Resultant force = 5N + 12N = 17N
Using the minimum magnitude:
Resultant force = 12N - 5N = 7N
Therefore, the resultant force will have a magnitude between 7N and 17N, depending on the direction and angle between the two forces.
