Answer:
|B - A| = 12.92 units
Explanation:
In order to find the magnitude of B-A vector, we first write A and B in Vector Notation:
A = Aₓ i + Ay j
A = 7.6 i - 9.2 j
B = Bₓ i + By j
B = -5.1 i - 6.8 j
So, there difference will be:
B - A = (-5.1 i - 6.8 j) - (7.6 i - 9.2 j)
B - A = -12.7 i + 2.4 j
Now, the magnitude of this vector can be found out by using the formula:
|B - A| = √[(x-component)² + (y-component)²]
|B - A| = √[(-12.7)² + (2.4)²]
|B - A| = 12.92 units
We will see that the magnitude of the difference of the vectors is 12.92
How to get the difference of two vectors?
Here we have two vectors:
A = <7.6, -9.2>
B = <-5.1, -6.8>
To get the difference we just subtract the correspondent components:
B - A = <Bx - Ax, By - Ay> = <-5.1 - 7.6, -6.8 - (-9.2)> = <-12.7, 2.4>
The magnitude of that vector is just:
[tex]M = \sqrt{(2.4)^2 + (-12.7)^2} = 12.92[/tex]
