A battery of emf \( \varepsilon_{0}=12 \mathrm{~V} \) is connected across a \( 4 \mathrm{~m} \) long uniform wire having resistance \( 4 \Omega / \mathrm{m} \). The cells of small emfs \( \varepsilon_{1}=2 \mathrm{~V} \) and \( \varepsilon_{2}=4 \mathrm{~V} \) having internal resistance \( 2 \Omega \) and \( 6 \Omega \) respectively, are connected as shown in the figure. If galvanometer shows no deflection at the point \( N \), the distance of point \( N \) from the point \( A \) is equal tohttps://bit.ly/YTAI_PWAP https://www.pw.live
