Figure shows a meter bridge (which is nothing but a practical Wheatstone Bridge) consisting of two resistors X and Y together in parallel with a meter long constantan wire of uniform cross-section. With the help of a movable contact D, one can change the ratio of the resistances of the two segments of the wire until a sensitive galvanometer G connected across B and D shows no deflection. The null point is found to be at a distance of 30 cm from the end A. The resistor Y is shunted by a resistance of 12.0 Ω Ω and the null point is found to shift by a distance of 10 cm. Determine the resistance of X and Y.
