Chapter 9: Q. 33 (page 621)

Find v

role="math" localid="1646774471795" v=3i-6j-2k

Short Answer

Expert verified

The norm of the vector v=3i-6j-2kisv=7

Step by step solution

01

Step 1. Give data

Given vector is

v=3i-6j-2k

02

Step 2. Norm of vector

Use formula of the norm of a vector v=ai+bj+ck

localid="1646774875415" ||v||=a2+b2+c2

so norm of the vector v=3i-6j-2kis

localid="1646774557805" v=32+-62+22v=9+36+4v=49v=7
