Question

Find the magnitude of vector A = i - 2j + 3k O V14 10 O4

Answer 1

`|A|=√(1^2+(-2)^2+(3)^2)=3.74`

Step-by-step explanation:

Given that,

Vector
`A=i-2j+3k`............(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 :

`|R|=√(x^2+y^2+z^2)`

In equation (1),

x = 1

y = -2

z = 3

So, the magnitude of vector A is given by :

`|A|=√(1^2+(-2)^2+(3)^2)`

|A| = 3.74

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