MCQ
The dimensions of inter atomic force constant are
- ✓$M T^{-2}$
- B$M L T^{-1}$
- C$M L T^{-2}$
- D$M L^{-1} T^{-1}$
✓
Answer
Correct option: A.
$M T^{-2}$
(a)
$K=Y \times r_0=\left[M L^{-1} T^{-2}\right] \times[L]=\left[M T^{-2}\right]$.
$Y=\text { Young's modulus and } r_0=\text { Interatomic distance }$
$K=Y \times r_0=\left[M L^{-1} T^{-2}\right] \times[L]=\left[M T^{-2}\right]$.
$Y=\text { Young's modulus and } r_0=\text { Interatomic distance }$
