MCQ
The dimensions of inter atomic force constant are
  • ✓
    $M{T^{ - 2}}$
  • B
    $ML{T^{ - 1}}$
  • C
    $ML{T^{ - 2}}$
  • D
    $M{L^{ - 1}}{T^{ - 1}}$
✓

Answer

Correct option: A.
$M{T^{ - 2}}$
a
(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
