આપેલ આકૃતિમાં, જો બે તારના પરિમાણો સમાન હોય, પરંતુ ધાતુઓ અલગ હોય, તો યંગનું મોડ્યુલસ ........ 

A

$A$ કરતાં $B$ વધારે 

B

$B$ કરતાં  $A$ વધારે 

C

$A$ અને $B$ સમાન. 

D

આપેલ તમામ 

Solution

(a)

At same value of load

$A$ has less elongation than $B \quad \ldots (1)$

$\frac{F L}{A Y}=\Delta L$    $\left\{\begin{array}{l}\because L, A \text { are same } \\ F \text { – Load is also taken same }\end{array}\right\}$

So $\frac{1}{Y} \propto \Delta L \quad \ldots (2)$

Using conditions $(1)$ and $(2)$

We can say

$Y_A > Y_B$    $\{$ Young's modulus of $A$ greater than $B\}$
