Question

A steel wire is stretched by a weight of 400N. If the radius of the wire is doubled, how
will Young's modulus of the wire be affected ?​

Answer 1

Answer:

If the radius of the wire is doubled,how will the young's modulus of the wire be effected? Young's modulus of a material depends on the nature of material and is independent of its dimensions. Therefore y of the steel will not be affected due to change of the radius.
