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

A resistance of 2 Omega is connected across one gap of a meter bridge (the length of the wire is 100 cm and an unknown resistance, greater than 2 Omega , is connected across the other gap. When these resistance are interchanged, the balance point shifts by 20cm . Neglecting any corrections, the unknown resistance is. (a) 3 Omega (b) 4 Omega ( c) 5 Omega (d) 6 Omega .

A resistance of 2 Omega is connected across one gap of a meter bridge (the length of the wire is 100 cm and an unknown resistance, greater than 2 Omega , is connected across the other gap. When these resistance are interchanged, the balance point shifts by 20cm . Neglecting any corrections, the unknown resistance is. (a) 3 Omega (b) 4 Omega ( c) 5 Omega (d) 6 Omega .

A resistance of 5Omega is connected across the left gap of a metrebridge and unknown resistance which is greater than 5Omega is connected across the right gap. When these resistances are interchanged the balancing length is found to change by 20cm. What is the value of the unknown resistance?
