Question
A wire of length Land radius
rigidly fixed at one end. On stretching the other end of the wire with a force F, the increase in its length is
If another wire of same material but of length 2L and radius
is stretched with a force 2F, the increase in its length will be
The correct answer is: 
Young’s modulus 

Since for same material Young’s modulus is same,
