In a metre bridge expt, when the resistances in the gaps are interchanged the balance point is increases by 10 cm. The ratio of the resistances is

In a metre-bridge experiment, when the resistances in the gaps in the gaps are interchanged, the balance-point did not shift at all. The ratio of resistances must be

The points in a metre bridge is at 35.6 cm. if the resistances in the gaps are interchanged, the new balance point is

The balance point in a meter bridge is 45cm .If the resistances in the gaps are interchanged the new balance point is

A resistance of 2Omega is connected across one gap of a metre-bridge(the length of the wire is 100 cm) and an unknown resistance, greater than 2Omega , is connected across the other gap. When these resistances are interchanged, the balance points shifts by 20 cm. Neglecting any corrections, the unknown resistance is

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
