The potential difference between positions (mathrm{a}) and (mathrm{b}) in Figure P31.51 is (6 mathrm{~V}), and (R_{1}=4.0 Omega,

Question:

The potential difference between positions $\mathrm{a}$ and $\mathrm{b}$ in Figure P31.51 is $6 \mathrm{~V}$, and $R_{1}=4.0 \Omega, \mathscr{E}_{1}=10.0 \mathrm{~V}$, and $\mathscr{E}_{2}=5.0 \mathrm{~V}$. What is the value of the resistance $R_{2}$ ?
