Chemistry - Atomic Structure Question with Solution | TestHub

$$\begin{array}{rl}& \lambda =\frac{h}{mv}\\ & h=6.6\times 10^{-34}\mathrm{J}-\mathrm{s}\\ & m=1000\mathrm{kg}\\ & v=36\mathrm{km}/\mathrm{hr}=\frac{36\times 10^3}{60\times 60}\mathrm{m}/\sec =10\mathrm{m}/\sec \\ & \therefore \lambda =\frac{6.6\times 10^{-34}}{10^3\times 10}=6.6\times 10^{-38}\mathrm{m}\\ & \end{array}$$
