Answer:

[tex]|A|=\sqrt{1^2+(-2)^2+(3)^2}=3.74[/tex]

Explanation:

Given that,

Vector [tex]A=i-2j+3k[/tex]............(1)

We need to find the magnitude of vector A. Let us suppose vector in the form of, R = xi + yj + zk. Its magnitude is given by :

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

In equation (1),

x = 1

y = -2

z = 3

So, the magnitude of vector A is given by :

[tex]|A|=\sqrt{1^2+(-2)^2+(3)^2}[/tex]

|A| = 3.74

So, the magnitude of given vector is 3.74. Hence, this is the required solution.
