Question

Electric field intensity due to long non conducting solid cylinder

Answer 1

Positive charge is distributed throughout a solid non-conducting cylinder of radius 'b ' and infinite length. The charge density increases with radius according to ρ = ρ o ρo( r 2 / b 2 r2/b2), where ρ o ρo is a constant (evidently equal to the charge density at the surface of the cylinder). Find the electric field intensity, E, as a function of radius, outside the cylinder.
