Three thin, concentric, conducting spherical shells have radii \(R\), \(2R\), and \(3R\), and carry net charges of \(+2Q\), \(-3Q\), and \(+5Q\), respectively. Three locations in space are designated as follows: point \(P_1\) is at distance \(r = 1.5R\), point \(P_2\) is at distance \(r = 2.5R\), and point \(P_3\) is at distance \(r = 4.0R\) from the common center. Which of the following correctly ranks the magnitudes of the electric fields, \(E_1\), \(E_2\), and \(E_3\), at points \(P_1\), \(P_2\), and \(P_3\), respectively?
