Question

the mean distance between the atoms of irons is 3 *10^-10m and interatomic force constant for iron is7N/m .the young's modulus of elasticity for iron is​

Answer 1

Explanation:

As we know that,

Interatomic force constant = Young's modulus × mean atomic distance

=> 7n/m

$= > young \: modulus \: \times \frac{7}{3 \times 10 {}^{ - 10} } n \: m {}^{2}$

$= > 2.33 \times 10 {}^{ - 10} \: nm {}^{2}$
