Q. The dimensions of inter atomic force constant are
A) $MT^{- 2}$
B) $MLT^{- 1}$
C) $MLT^{- 2}$
D) $ML^{- 1}T^{- 1}$
Explanation
$K = Y \times r_{0} = \left\lbrack ML^{- 1}T^{- 2} \right\rbrack \times \lbrack L\rbrack = \lbrack MT^{- 2}\rbrack$ $Y$=Young’s modulus and $r_{0} =$ Interatomic distance
