Between two concentric spherical surfaces of radius R₁ = 10cm and R₂ = 20 cm an electric charge with uniform density is distributed p=26.58-10-8C/m³. Determine the expression of the electrostatic field E(r) as a function of the distance r from the center of the system. If an electron is left on the outer surface, how long does it take to pass through the inner cavity?
