Question
The bulk modulus of a metal is 1010 N/ m2 and Poisson′s ratio 0.20 If average distance between the molecules is 3A then the interatomic force constant
Options
A.5.4N/m
B.7.5N/m
C.7.5N/m
D.30N/m
Solution
Young′s modulus
Y = 3K(1-2σ) = 3 × 1010(1 - 2 × 0.2)
1.8 × 1010 N/m2
Y = 3K(1-2σ) = 3 × 1010(1 - 2 × 0.2)
1.8 × 1010 N/m2
