Consider u = (5,-2) and v= (10,-4). What is the relationship between u and v?
The relationship between the both component would be v = 2u. So, the option A. The vectors point in the same direction is correct.
If we have given a vector v of initial point A and terminal point B
v = ai + bj
then the components form as;
AB = xi + yj
Here, xi and yj are the components of the vector.
Consider u = (5,-2) and v= (10,-4).
Now, multiply each component by 2
2u = 2 (5, - 2 )
= (10, - 4) = v ,
then
v = 2u
Hence, the relationship between the both component would be v = 2u.
So, the option A. The vectors point in the same direction is correct.
