The dimensions of inter atomic force constant are
A$M{T^{ - 2}}$
B$ML{T^{ - 1}}$
C$ML{T^{ - 2}}$
D$M{L^{ - 1}}{T^{ - 1}}$
Solution
(a) $K = Y \times {r_0}$= $[M{L^{ – 1}}{T^{ – 2}}] \times [L]$= $[M{T^{ – 2}}]$
$Y$= Young's modulus and ${r_0}$ = Interatomic distance
$Y$= Young's modulus and ${r_0}$ = Interatomic distance
