Homework Statement
Five vectors are listed below. Select them in order of increasing magnitudes, from shortest to longest. If B is smallest, then A, C, D, and finally E is the largest, enter BACDE (Note: If of equal length, then enter in the order listed.)
A) 23i-31j-17k
B) 36j+26k
C) 43j
D) 20i-34j-20k
E) 30i+30j
Homework Equations
magnitude = sqrt (i^2 + j^2 + k^2)
The Attempt at a Solution
I found:
A = 42.178
B= 44.407
C = 43
D = 44.226
E 42.426
I ranked: AECDB or even follow the order list: AECBD => It's showing wrong?
Could anyone explain what's going on? I'm really confused because I think I'm doing the right way!
Thanks!
