a simple meter-bridge circuit, the both gaps are bridge by coils P and Q having the smaller resistance. A balance is obtained when the jockey key makes contact at a point of the bridge wire 40 cm from the P end. On shunting the coil Q with a resistance of 50Ω the balance point is moved through 10 cm . What are the resistance of P and Q
