Two cells \( A \) and \( B \) of e.m.f. \( 2 \mathrm{~V} \) and \( 1.5 \mathrm{~V} \) respectively, are connected as shown in figure through an external resistance \( 10 \Omega \). The internal resistance of each cell is \( 5 \Omega \). The potential difference \( E_{A} \) and \( E_{B} \) across the terminals of the cells \( A \) and \( B \) respectively are

(a) \( E_{A}=2.0 \mathrm{~V}, E_{B}=1.5 \mathrm{~V} \)
(b) \( E_{A}=2.12 \mathrm{~V}, E_{B}=1.375 \mathrm{~V} \)
(c) \( E_{A}=1.875 \mathrm{~V}, E_{B}=1.625 \mathrm{~V} \)
(d) \( E_{A}=1.875 \mathrm{~V}, E_{B}=1.375 \mathrm{~V} \)
