Find the separation vector r from the source point (2,8,7) to the field point (4,6,8). determine its magnitude (r), and construct the unit vector ˆr.

magnitude =3 unit vector

Step-by-step explanation:

We have given source point

And the field point

Resultant vector

The resultant vector

Magnitude of the vector

Now we have to find the unit vector

So unit vector

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

the answer is 48m^2!
