Two forces act on an object. The magnitude of the net force acting on the object
a. equals the sum of the magnitude of the two forces
b. equals the difference in the magnitudes of the two forces
c. equals the average of the two forces
d. cannot be determined from the given information
d,
force is vector, you need both magnitude and DIRECTION to find anything about the sum.
Equal to the net force acting on the object
The correct answer is a. The magnitude of the net force acting on an object equals the sum of the magnitude of the two forces. This is due to the principle of vector addition, where forces are added together when acting in the same direction.
To determine the magnitude of the net force acting on an object when two forces are involved, you need to understand the concept of vector addition.
When multiple forces act on an object, you can find the net force by adding the individual forces together using vector addition. The net force is the vector sum of the forces, taking into account both their magnitudes and directions.
Mathematically, if two forces A and B are acting on an object, the net force (F_net) can be obtained by adding the vectors A and B:
F_net = A + B
So, the correct answer is (a) "equals the sum of the magnitude of the two forces."
