How is the magnitude of a force represented on a free body diagram?

The magnitude of force as a vector is represented by the length of vector.

Whenever we need to represent any physical quantity (let us say force), then often need to parameters, first is magnitude and second is direction. The magnitude is a numerical value that determines the exact amount and direction determines the path or way of application.

Thus, we can conclude that the magnitude of force as a vector is represented by the length of vector.

The length of the vector.

Explanation:

Forces are typically represented by vectors, which is an arrow in laymen’s terms. Vectors have a direction and a magnitude. The magnitude (or greatness of it) is shown by the length. The arrow represents the direction.

the answer is to check all of them! they all apply well at least i think so!
