The resistance of the meter bridge \( A B \) is given figure is\( 4 \Omega \). With a cell of emf \( E=0.5 \mathrm{~V} \) and rheostat resistance \( R_{h}=2 \Omega \) the null point is obtained at some point \( J \). When the cell is replaced by another one of emf \( E=E_{2} \) the same null point \( J \) is found for \( R_{h}=6 \Omega \). The emf \( E_{2} \) is
