Question

is vector AB= b-a or a-b​

Answer 1

Step-by-step explanation:

Vectors A-B and B-A are the same in magnitude but different in direction. Here are two examples. If the vectors are in the same dimension (in line) then A-B and B-A are equal in magnitude but different in direction.

Answer 2

Answer :

Vector $AB$ $=b-a$

Tip:

• A vector is an object that has both a magnitude and a direction.  
• The direction of the vector is from its tail to its head.

Step

Step 1 of 1:

We know, from the definition of vector

Vector $AB$ $=b-a$

Because, $A$ is the starting point and $B$ is the ending point.
