A resistance of 2 2 is connected across one gap of a metre-bridge (the length of the wire is 100 cm) and an unknown resistance, greater than 202, is connected across the other gap. When these resistance are interchanged, the balance point shifts by 20 cm. Neglecting any corrections, the unknown resistance is (A) 3 Q2 (C) 5 () 4 (D) 6 22 A resistance of 2 2 is connected across one gap of a metre-bridge (the length of the wire is 100 cm) and an unknown resistance, greater than 202, is connected across the other gap.
