Chapter 9: Q. 37 (page 603)

In Problem, find

v=i-j

Short Answer

Expert verified

The magnitude of v,v=2

Step by step solution

01

Step1. Given information

v=i-j

We know that if,

v=xi+yjthenmagnitudeofv,v=x2+y2

02

Step2. Calculating the magnitude of v

v=i-j

compare x and y with 1 and -1

v=12+(-1)2v=1+1v=2
