In Searle's experiment, which is used to find Young's modulus of elasticity, the diameter of experimental wire is (measured by a scale of least count ) and length is (measured by a scale of least count . A weight of causes an extension of (measured by a micrometer of least count ). Find maximum possible error in the value of Young's modulus. Screw gauge and meter scale are free from error.
Young's modulus of elasticity is given by
Substituting the values, we get
=0.0489
