P.4-3 Lightning strikes a lossy dielectric sphere-1.2€0, 0 = 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 a) the electric field intensity both inside and outside the sphere, b) the current density in the sphere. P.4-4 Refer to Problem P.4-3. a) Calculate the time it takes for the charge density in the sphere to diminish to 1% of its initial value. b) Calculate the change in the electrostatic energy stored in the sphere as the charge density diminishes from the initial value to 1% of its value. What happens to this energy? c) Determine the electrostatic energy stored in the space outside the sphere. Does this energy change with time?
