Q179 · Physics

A resistance wire connected in the left gap of a metre bridge balances a 10 Ω\Omega 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 1 Ω\Omega of the resistance wire is :

  1. 11.0×10−21.0\times10^{-2} m
  2. 21.0×10−11.0\times10^{-1} mOfficial answer
  3. 31.5×10−11.5\times10^{-1} m
  4. 41.5×10−21.5\times10^{-2} m
