In Searle's method to find Young's modulus of a wire, when a force of 1 5 ~kg -wt is applied at its free end, the length of wire is ' a '. When force of 2 5 kg-wt is applied, the length of wire is 'b'. What would be its original length?

Options

  1. Ab - a
  2. Bb - a 4
  3. C2 5 a -1 5 ~b
  4. D2 5 ~b -1 5 a

Correct answer

C. 2 5 a -1 5 ~b
