In the figure, battery 1 has an electromotive force (emf) \( \varepsilon_1 = 14.0 \, \text{V} \) and an internal resistance \( r_1 = 0.040 \, \Omega \). Battery 2 has an emf \( \varepsilon_2 = 14.0 \, \text{V} \) and an internal resistance \( r_2 = 0.018 \, \Omega \). The batteries are connected in series with an external resistance \( R \).**Problem Statement:****(a)** What \( R \) value makes the terminal-to-terminal potential difference of one of the batteries zero?**(b)** Which battery is that?**Circuit Diagram Description:**The circuit diagram shows two batteries, each with its emf and internal resistance, arranged in series. The external resistance \( R \) is also in series with these batteries. The direction of the emf for both batteries is indicated upwards.**Answer input fields:**- For part (a), there is a numeric input field to enter the value of \( R \) with a dropdown to select units, defaulting to \( \Omega \).- For part (b), a dropdown menu allows selection of either "battery 1" or "battery 2".
