## 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!
