Question

In the integral \[\int\limits_{V}^{}\rho _{v}dV\] to determine the enclosed charge, can \[\rho _{v}dV\] be changed to \[\rho _{v} \] dot Ads??

Answer 1

is this across an x,y,z region?

Answer 2

this is in spherical coordinate system...

Answer 3

... that one has something like \(\rho~sin^2\) if memory serves

Answer 4

\[\rho^2~sin(\phi)~ddd\]

Answer 5

yes, for us rho is R...

Answer 6

but would it be possible then to change the differential volume to area multiplied by the differential length? I was working through a test and it's been done here, but it's the first time that I'm seeing this being done...

Answer 7

im not up to snuff on sphericals enough to be certain

Answer 8

Oky, but thanks anyway.
