A M Puz S B R Diagram shows a meterbridge wire AB has uniform cross sectional area and length L M is mid point of wire AB Resistivity of wire AM is p and that of MB is 2p Steady current is flowing in circuit It is observed that when jocke touches mid point of wire AM then deflection in galvanometer is zero Find ratio of resistance S and R
