Two forces acting on an object are parallel and act in the same direction (westerly). The mangnitude of one of the forces is 60N and the resultant is 80N. What is the magnitude of the other force ???
To find the magnitude of the other force, we can use the concept of vector addition. Since the forces are parallel and act in the same direction, we can simply subtract the magnitude of the known force from the magnitude of the resultant force to find the magnitude of the unknown force.
Let's denote the unknown force as F2.
Magnitude of the resultant force = Magnitude of Force 1 + Magnitude of Force 2
80N = 60N + Magnitude of Force 2
To find the magnitude of Force 2, we can rearrange the equation:
Magnitude of Force 2 = 80N - 60N
Magnitude of Force 2 = 20N
Therefore, the magnitude of the other force is 20N.
To find the magnitude of the other force, we can use the concept of vector addition and subtraction. Since the two forces are parallel and act in the same direction, their magnitudes can be directly added to find the resultant force.
Let's call the magnitude of the other force "F2". We know that the magnitude of one force is 60N and the resultant magnitude is 80N.
Using vector addition, we have:
F1 + F2 = Resultant force
Substituting the known values:
60N + F2 = 80N
To find the magnitude of the other force, we need to isolate F2. Let's solve for F2:
F2 = Resultant force - F1
Substituting the values we have:
F2 = 80N - 60N
F2 = 20N
Therefore, the magnitude of the other force (F2) is 20N.
F1+F2 = 80.
60 + F2 = 80,
F2 =
