Question

The Young's modulus of a rod of length
L and radius R is Y. The rod is cut into
two parts of equal length L/2, then
Young's modulus of each part will be
"A) Y (B) Y/2 (C) Y/4 (D) 4Y​

Answer 1

Answer:

Young's modulus of the rod will remain same as initial "Y"

Explanation:

Young's Modulus of the given material of the rod only depends on its intrinsic properties

So we can say that Young's modulus of the rod depends only on its material but it is independent of the length and radius.

So here we know that the Young's modulus of the rod is initially Y and then if the rod is divided into two or more parts with change in it's radius the material will remains unchanged

So here the Young's modulus will remains Same
