I am taking a lightning class for my atmospheric science masters degree. However its been awhile and Im having trouble with remembering how to do the physics portion of it. I hope someone can help me!(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

I have an electric field [itex]\vec{}E[/itex]=E[itex]_{}x[/itex][itex]\widehat{}X[/itex]+E[itex]_{}y[/itex][itex]\widehat{}Y[/itex]+E[itex]_{}z[/itex][itex]\widehat{}Z[/itex] Find the divergence and curl of this electric field. I have done this with no problem. The second part is where Im confused. I have to find the space density charge of [itex]\vec{}E[/itex]=E(r)[itex]\dot{}r\widehat{}[/itex]

2. Relevant equations

I have an equation for space charge density but am unsure how to derive it. The space charge equation I have is ([itex]\rho[/itex]/[itex]\epsilon[/itex])=delta dot E

Can some one give me some pointers on even how to find a space charge denstiy?\

Thanks
