Problem:Consider a long, cylindrically symmetric charge distribution. where the charge is uniformly distributed throughout the cylindrical volume up to a radius d/2 as shown in the figure. The constant, linear charge density (charge per unit length) is given by ). a) Using Gauss' Law, derive an expression for the electric field E(r) evaluated at some radius r beyond the charge distribution (be. r > d/2). This can be done by considering a cylindrical Gaussian surface, also centered at the origin. A clear explanation leading to your final expression is required for full marks. (2 marks)
