In Searle's experiment for Young's modulus, the experimental wire and the reference wire should be (more than one option may be correct)
Options:(select one or more)
Answer:
A, B, D
Solution:
The two wires should be identical in material, length and area of cross-section so that thermal expansion and sagging effects cancel; long thin wires give a measurable extension for small loads.
Only the experimental wire is loaded, so (C) is wrong.
