Question

I know this is math but it kinda is physics related so maybe one of u guys can help me out
Find the vector flux of G=2yi+3xj-zk through the cylinder x^2+y^2=4 and
2≤z≤−2

Answer 1

vector field through a paraboloid ...
same people are here on physics group .... LOL

Answer 2

hahah i know but i will get attn here.In the math group my question gets swallowed

Answer 3

yeah ... math group is getting pretty big, i saw you question this afternoon, but didn't attempt it.

Answer 4

like i cant figure out how to find the normal vector and stuff and i feel terrible driving everyone crazy but like i was banking on my tutor coming cuz i cldnt get this concept and like he backed out on me everyday. I guess its time to find a new one

Answer 5

Oo ... it's a sphere this time ... last time it was a paraboloid

Answer 6

LOL ... i would like to understand it too ... i thought you had references last time.

Answer 7

well like its a cylinder this time no?

Answer 8

looks like a circle

Answer 9

Oo ... there was no z ... which means it is a cylinder

Answer 10

using divergence theorem it can be done easily ... but i don't think you are doing it with Gauss Divergence theorem.

Answer 11

Just tell me what G stands for. I will try to solve it :D

Answer 12

No No. Looks like college level, I am have just finished my +2

Answer 13

G is a vector ... surface integral of vector in the cylindrical surface gives flux through it.

Answer 14

hahaha sorry guys I posted this question in the math group and it had gotten lost but amistre found it and is answering it so i was just switching back and forth

Answer 15

i believe my final result was zero; if we can verify or deject that it might be useful tho :)

Answer 16

from divergence theorem it should be
(2+3-1) pi r^2 h
