Answer:
8.9 units
Explanation:
The magnitude of a 3-D vector B can be calculated by using the formula:
[tex]|B| = \sqrt{B_x^2+B_y^2+B_z^2}[/tex]
where [tex]B_x, B_y, B_z[/tex] are the x, y and z components of the vector, respectively.
For the vector in the problem:
[tex]B_x = 2.2\\B_y = 6.6\\B_z = 5.5[/tex]
Substituting into the equation, we find the magnitude of B:
[tex]B=\sqrt{2.2^2+6.6^2+5.5^2}=8.9[/tex]
So, the magnitude of B is 8.9 units.
