Aspherically symmetric charge distribution has a charge density given by rho = a/r , where a is constant. find the electric field as a function of r. (suggestion: the charge within a sphere of radius r is equal to the integral of rho dv, where r extends from 0 to r. to evaluate the integral, note that the volume element dv for a spherical shell of radius r and thickness dr is equal to 4πr2dr.) (use epsilon_0 for ε0, a, r, and r as necessary.)
