Two cells $A$ and $B$ of emf $2 \text{ V}$ and $1.5 \text{ V}$ respectively, are connected as shown in the figure through an external resistance $10 \text{ } \Omega$. The internal resistance of each cell is $5 \text{ } \Omega$. The potential difference $V_{A}$ and $V_{B}$ across the terminals of the cells $A$ and $B$ respectively are:

  • A
    $V_{A}=2.0 \text{ V}, V_{B}=1.5 \text{ V}$
  • B
    $V_{A}=2.125 \text{ V}, V_{B}=1.375 \text{ V}$
  • C
    $V_{A}=1.875 \text{ V}, V_{B}=1.625 \text{ V}$
  • D
    $V_{A}=1.875 \text{ V}, V_{B}=1.375 \text{ V}$
