Physics Elasticity Question 108
Question: The interatomic distance for a metal is $ 3\times {{10}^{-10}},m $ . If the interatomic force constant is $ 3.6\times {{10}^{-9}},N/\mathring{A} $ , then the Young’s modulus in $ N/m^{2} $ will be
Options:
A) $ 1.2\times 10^{11} $
B) $ 4.2\times 10^{11} $
C) $ 10.8\times {{10}^{-19}} $
D) $ 2.4\times 10^{10} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ Y=\frac{3.6\times {{10}^{-9}}N/{\mathring{A}}}{3\times {{10}^{-10}}m} $
$ =1.2\times 10^{11}N/m^{2} $
