(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1. Lightning strikes a dielectric sphere (Relative Permeability=1.2, Conductivity=10 S/m) of radius 0.1 m at time t=0, depositing uniformly in the sphere a total charge 1 mC. Determine for all t,

theelectric field intensity - E(Volts/m) ¤t density - J(Ampere/m^2) both

inside and outside the sphere.

2. Relevant equations

Ohm's Law: J = 10 S/m(conductivity) * E

[So if I know one then I know the other]

Electric Field @ Distance R

E= (q[tex]\widehat{R}[/tex]) / (4 [tex]\pi[/tex] [tex]\epsilon[/tex] R [tex]^{2}[/tex])

3. The attempt at a solution

Don't know where to begin on this one. Almost all of my equations have to do with a dielectric object sitting inside of an E field. Does the charge go dissipate over time? If so then it is asking for an equation correct? Could this be modeled as a point charge in some way?

I'm not looking for an answer only a direction please.
