In comparing the resistance of two cells P and Q with a sides wire bridge, a balance point is obtained when the sliding contact is 30 cm from the zero end of the wire. The resistances P and Q are interchanged and the balance is obtained at 120 cm from the same emf. Find the ratio of the resistance P and Q and the length of the bridge wire

When an unknown resistance and a resistance of 4Omega are connected in the left and right gaps of a meterbridge, the balance point is obtained at 50 cm. the shift in the balance point if a 4Omega resistance is now connected in parallel to the resistance in the right gap is
