Sorry And here's your smoke to shore Brought to you

00:04

by vector diagrams Yes What you thought was just doodling

00:08

is now part of advanced physics Congrats baby All right

00:13

check the falling diagram this thing here like you grandpas

00:19

given these vector fields of equal magnitude in which direction

00:23

will the resulting vector field go And here the potential

00:27

answers that way Vector field Before we jump into this

00:32

let's take another look at our vector field diagram this

00:36

puppy right here Well there are five vertical vectors and

00:39

three horizontal doctors say one for five and a one

00:42

two three But notice that the question states the vector

00:45

fields have the same magnitude So it's important that we

00:48

don't get thrown off by the number of lines we

00:50

see They're just representative of a plane If we know

00:55

we're dealing with two vector fields of equal magnitude going

00:58

in different directions How do we figure out the net

01:01

Vector field Well we have to add the vectors do

01:05

that We take one vector from each field and place

01:08

them tip to tail Then we connect the ends to

01:11

find the net factor like this Well that means our

01:15

option d is the correct answer Now this question the

01:18

answer is pretty straight forward once we know how to

01:20

put the vectors together After all we're just drawing a

01:23

line to make a right triangle But if the diagrams

01:25

aren't is straight and need is this one or if

01:28

we just can't visualize what it's supposed to look like

01:31

Well we can sketch you draw the line ourselves to

01:33

make it clear That's right We may have to doodle

01:35

on our ap physics test that's just fine We just

01:39

need to make sure we're drawing vector diagrams and pink

01:42

unicorn and next time we're day driving Well that's the

01:46

kind of job that a theoretical physicist will do Remember 00:01:50.314 --> [endTime] sheldon man even when you're trying to waste time
