The intermolecular vander Waals potential is inversely proportional to $\mathrm{r}^{6}$. The corresponding force is proportional to

(a)$\frac{1}{\mathrm{r}^{5}}$

(b)$\frac{1}{r^{6}}$

(c)$\frac{1}{\mathrm{r}^{7}}$

(d)$\frac{1}{\mathrm{r}^{12}}$

Answer

Answer: C ✓ checked by 4AB · confidence high

Explanation

F = −dV/dr; for V ∝ −1/r⁶ the force ∝ 1/r⁷.
