A resistance wire connected in the left gap of a metre bridge balances a 10Ω resistance in the right gap at a point which divides the bridge wire in the ratio 3 : 2. If the length of the resistance wire is 1.5 m, then the length of 1Ω of the resistance wire is :
(1) 1.0 × 10–1 m
(2) 1.5 × 10–1 m
(3) 1.5 × 10–2 m
(4) 1.0 × 10–2 m
