Question

A force F doubles the length of wire of cross section a The Young modulus of wire is​

Answer 1

Answer:

F/2a

Explanation:

As a young modulus is given by

Y=F/a .L/∆L

from the above we conclude that

Y'=2Y

THAT IS young modulus becomes 2 times to its original value

so F/2a

Answer 2
