Answer 2

Explanation:

It is given that,

Vector A, $v_A=4i-3j+k$

Vector B, $v_B=9i+2j+2k$

Let |A| and |B| are the magnitude of vector A and vector B. It can be calculated as :

$|A|=\sqrt{x^2+y^2+z^2}$

$|A|=\sqrt{4^2+(-3)^2+1^2}$

|A| = 5.09

$|A|=\sqrt{x^2+y^2+z^2}$

$|A|=\sqrt{9^2+(2)^2+2^2}$

|B| = 9.43

Hence, this is the required solution.
