Answer:

PLZ MARK ME AS BRAIN LIST

Explanation:

Consider the expression for Young’s modulus.

Y=AΔLFL

ΔL=AYFL

Where A is the area, F is the applied force, ΔLis the increase in length.

So,

ΔL=πr2YFL

ΔL∝r21

l1l2=(r2r1)2

=(d2/2d1/2)2

=(n)2

l2=n2l1

Hence, on applying the same load, the length is increased by a factor of n2.
