A solid sphere of radius R has electric charge density given by  𝜌 = a/r , where a is constant. Find the electric field within the charge distribution as a function of r. Note: The volume element dV for a spherical shell of radius r and thickness dr is equal to 4𝜋r2dr. (Use the following as necessary: a, r, and 𝜀0. Consider that a is positive.)
