A silver atom in a solid oscillates in simple harmonic motion in some direction with a frequency of $\displaystyle 10^{12} / \mathrm{sec}$. What is the force constant of the bonds connecting one atom with the other ? (Mole wt. of silver $\displaystyle =108$ and Avagadro number $\displaystyle =6.02 \times 10^{23} \mathrm{gm}$ mole $\displaystyle ^{-1}$ )
