Can magnitude of A-B vector be the same as B-A?
The magnitude is the same, the direction vector is not.
Why can vectors be used to represent forces?
A vector is a quantity with magnitude and direction. Since force has magnitude and direction, it is a vector
A direction a vector is drawn indicates the magnitude of the vector?
No. The size of the size of the vector drawn indicates the magnitude.
How do you find a vector if you have itsmagnitude and its direction given?
That's it! You know everything there is to know about it. It's not as if you have to wander through a crowd of vectors and find one that matches the description. "Find the vector" means figure out its magnitude and direction. If the problem already gave you the magnitude and direction, then it's unlikely that it's asking you to 'find' that same vector.
Physical meaning of vector?
A quantity involving direction and magnitude is called physically vector A quantity involving direction and magnitude is called physically vector
