Please help:)
I want to know what would happen if theta=45degrees? [File attached.]

Answer 1

@eyust707 Please help:)

Answer 2

Ive never studied E and M but I could think about it for a sec if you would like

Answer 3

k!

Answer 4

if theta is 45 then cos 45 = 1/rt2

Answer 5

just plug that into what youve written...

Answer 6

do you have any info about the vectors?

Answer 7

ya. very much

Answer 8

?

Answer 9

I mean I know basics of vectors.

Answer 10

no no were you given any information about the vectors

Answer 11

no.

Answer 12

assuming what youve posted is correct
with theta = 45 the electric flux would simply be equal to some value

Answer 13

k! it means it has nothing to do with something like max. flux or min. flux.

Answer 14

no! okay so assuming that we hold the magnitude of both the vectors constant and then only change theta we can see that the only function changeing the value of the dot product would be cos theta

Answer 15

what is the greatest cos theta can ever be?

Answer 16

1

Answer 17

and at what thetha would that be?

Answer 18

at theta= 0

Answer 19

yes!

Answer 20

ya

Answer 21

k! i have got it thanx.
