In Searl's experiment, which is used to find Young's Modulus of elasticity, the diameter of experimental wire is `D = 0.05cm` (measured by a scale of least count `0.001cm`) and length is `L = 110cm` (measured by a scale of least count `0.1cm`). A weight of `50N` causes an extension of `X = 0.125 cm` (measured by a micrometer of least count `0.001cm`). find the maximum possible error in the values of Young's modulus. Screw gauge and meter scale are free error.
