Chapter 9: Q. 38 (page 603)

In Problem, find

v=-i-j

Short Answer

Expert verified

The magnitude of v,v=2

Step by step solution

01

Step 1, Given the information

v=-i-j

WE know that if v (a,b) then the magnitude of v,

v=a2+b2
02

Step2. Calculating the magnitude 

v=-i-j

Compare a and b with -1 and -1

so the magnitude of v,

v=-12+-12v=2
