Question

In Searle's experiment to find Young's modulus the diameter of wire is measured as d = 0.05cm, length of wire is ???? = 125cm and when a weight, m = 20.0 kg is put, extension in wire was found to be 0.100 cm. Find maximum permissible error in Young's modulus (Y). Use : Y = mg????/(π/4) d²x. (a) 6.3% (b) 5.3% (c) 2.3% (d) 1%

Answer 1

Explanation:

In Searle's experiment to find Young's modulus, the diameter of wire is measured as D=0.05cm, the length of wire is L=125cm, and when a weight, m=20kg is the put, extension in wire was found to be 0.100cm. Find the maximum permissible error in Young's modulus (Y).
