# Can someone help out?

I tried to invoke Green's theorem but couldn't as Green's theorem is valid for 2D vector fields and here I have a 3D vector field.

Can someone help ?

by stokes theorem you would be able to convert this line integral into surface integral by the means of taking curl of line integral ie curl= cross product of vectors

@aryan goyat Bhaiya , I want to improve my physics. Please tell how to do it. Anything regarding books , problem books , websites , videos , contest problems etc. I want to clear NSEP this year and may it to OCSC atleast.

i think there is no place better than brilliant to improve your physics ,you can try mechanics problems by Deepanshu Gupta,Mvs Saketh,Ronak Agarwal as no can teach physics better than questions. i would also suggest you to complete irodov before NSEP , it will definately help and the next thing out in physics is to never give up in any kind of question , the more you think about it more good you become.I myself has now decided that i will weekly post one question with the title "Physics is Cool" and would try to post question from every topic ,each question carrying a new concept.

Thanks, Any theory book would definitely help.

though i don prefer reading physics but still i have seen people admiring hcv ,resnik and haliday,physics galaxy.

is there any relation between x,yand z are given like in some parametric form or any boundary condition

use stokes theorem for converting line to surface integral

Can you do it and show ? I tried.

Use Calvin Stokes Theorem maybe?

@Jake Lai , any ideas?

Stokes is for Surface integrals while here I have a line.
