Question

answer this question by steps I will mark as brainlist​

Answer 1

Answer:

Y = FL / (Ae)

For same material Y is constant and A is constant for two similar wires.

∴ FL / e = constant

Here F = mg

e1 / e2 = (m1 / m2) * (L1 / L2)

= (3/4) * (9/10)

= 27 / 40

Ratio of their extensions is 27 : 40
