A battery of emf `epsilon_0=10V` is connected across a `1m` long uniform wire having resistance `10Omega//m.` Two cells of emf `epsilon_1=2V` and `epsilon_2=4V` having internal resistance `1Omega` and `5Omega` respectively are connected as shown in the figure. If a galvanometer shows no deflection at the point `P`, find the distance of point `P` from the point `a`.

A battery of emf E_0=12V is connected across a 4 m long uniform wire having resistance 4Omega//m . The cell of small emfs epsilon_1=2V and epsilon_2=4V having internal resistance 2Omega and 6Omega respectivley are connected as shown in the figure. If galvanometer shows no diflection at the point N the distance of points N from the point A is equal to
