## anonymous 3 years ago 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??

is this across an x,y,z region?

2. anonymous

this is in spherical coordinate system...

3. amistre64

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

4. amistre64

$\rho^2~sin(\phi)~ddd$

yes, for us rho is R...

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...

7. amistre64

im not up to snuff on sphericals enough to be certain

Oky, but thanks anyway.
