Answer:

The magnitude of B is [tex]10.95\ units[/tex]

Explanation:

we know that

The magnitude of Vector B is

[tex]B=\sqrt{x^{2}+y^{2}+z^{2}}[/tex]

where

x,y and z are the components of vector B

we have

[tex]x=8.7\ units, y=1.4\ units,z=6,5\ units[/tex]

substitute

[tex]B=\sqrt{8.7^{2}+1.4^{2}+6.5^{2}}[/tex]

[tex]B=\sqrt{119.9}[/tex]

[tex]B=10.95\ units[/tex]
