Thanks for the reply.
If it as first uniformly distributed, then it will only be that way at t=0 correct?
since it will redistribute afterwards, the answer will be a piecewise function?

Homework Statement
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,
the electric field intensity - E(Volts/m) & current density - J(Ampere/m^2)...
