Question

can i get a little help with divergence diagrams?

Answer 1

@ganeshie8, can you help?

Answer 2

how many times u can try ?

Answer 3

4 attempts

Answer 4

ok try this :

0, negative, 0

Answer 5

no. not sure which is right and which is wrong though

Answer 6

try this

0, negative, positive

Answer 7

The middle one is definitely negative as it's moving toward the origin. The first one and third one can't be 0 as it's not in the same direction?

Answer 8

they are asking for divergence at a point, not the divergence of entire field hmm

Answer 9

0, -,+ worked. why?

Answer 10

That makes sense

Answer 11

create a sphere around P in first diagram

Answer 12

*circle i guess since we are in 2D

Answer 13

the fluid is entering from left side and leaving out from the right side

Answer 14

notice that the amount of fluid entering is SAME as the amount leaving because the magnitude of vector is not changing as you move from left to right

Answer 15

ok, so it's balanced. so it's 0

Answer 16

yes use the same trick for others

Answer 17

ok. thanks.

Answer 18

for the point in second vector field, more fluid is entering in compared to the amount leaving

Answer 19

that means the point is acting as a "sink" sucking in some of the fluid that entered in

Answer 20

the opposite is true for the point in 3rd diagram

Answer 21

ok. makes sense.
