Answer 2

Concept Introduction: Elasticity is the basic concept of Physics.

Given

We have been Given: If two wire of same material and of same length have ratio of their radii 1:3, then under the effect of same stretching force, their respective elongation will be in ratio.

To Find:

We have to Find: If two wire of same material and of same length have ratio of their radii 1:3, then under the effect of same stretching force, their respective elongation will be in ratio.

Solution:

According to the problem,

$\frac{ r_{1} }{ r_{2} } = \frac{1}{3}$

but Elasticity is inversely proportional to the square of the radius of the wire. there,

$\frac{ e_{1} }{ e_{2}} = \frac{ {3}^{2} }{ {1}^{2} } = 9 : 1$

Final Answer: The ratio of elasticity is

$9 : 1$
