A circuit is constructed from two batteries and two wires, as shown in the diagram below. Each battery has an emf of \( 1.6 \) volts. Each wire is \( 24 \mathrm{~cm} \) long, and has a diameter of \( 0.0007 \) meters. The wires are made of a metal which has \( 7 \mathrm{et} \) and labeled by a letter are in the interior of the wire. Which of these statements about the electric field in the interior of the wires, at the locations marked by "x"s, are true? Check all that apply. At every marked location the magnitude of the electric field is the same. The magnitude of the electric field at location \( \mathrm{G} \) is larger than the magnitude of the electric field at location \( \mathrm{F} \). At location D the electric field points to the right. Which of the following equations is a correct energy conservation (round-trip potential difference) equation for this circuit, along a round trip and continuing on around the circuit in the same direction)? \( \bigcirc-1.6 \mathrm{~V}+\mathbf{E}^{*}(0.24 \mathrm{~m})-1.6 \mathrm{~V}+\mathbf{E}^{*}(0.24 \mathrm{~m})=0 \) \( \bigcirc+1.6 \mathrm{~V}-\mathbf{E}^{*}(0.24 \mathrm{~m})+1.6 \mathrm{~V}-\mathbf{E}^{*}(0.24 \mathrm{~m})=0 \) \( \bigcirc-1.6 \mathrm{~V}+\mathbf{E}^{*}(0.24 \mathrm{~m})+1.6 \mathrm{~V}-\mathbf{E}^{*}(0.24 \mathrm{~m})=0 \) \( \bigcirc-1.6 \mathrm{~V}+\mathbf{E}^{*}(0.24 \mathrm{~m})=0 \) \( O+1.6 \mathrm{~V}-1.6 \mathrm{~V}=0 \) \( \bigcirc+1.6 \mathrm{~V}-\mathbf{E}^{*}(0.24 \mathrm{~m})=0 \) \( \bigcirc+1.6 \mathrm{~V}-\mathbf{E}^{*}(0.24 \mathrm{~m})-1.6 \mathrm{~V}+\mathbf{E}^{*}(0.24 \mathrm{~m})=0 \) What is the mannitude of the electric field at location F? \( E_{F}=\quad 1 / m \) Hnw manv olertrons per second enter the positive end of battery #2? | electrons/s If the cross-sectional area nf hnth wires were increased by a factor of 2, what would the be magnitude of the electric field at location F? new value of \( \boldsymbol{E}_{\mathrm{F}}=\mathrm{V} / \mathrm{m} \) Which of the diagrams below best shows the approximate distribution of excess charge on the surface of the circuit?
