Problem

Calculate the numerical value of the first Bohr radius of hydrogen using the following constants:

m = 9.11\times10^{-31}\,\text{kg}

e = 1.60\times10^{-19}\,\text{C}

\varepsilon_0 = 8.85\times10^{-12}\,\text{C}^2\text{N}^{-1}\text{m}^{-2}

and

h = 6.63\times10^{-34}\,\text{J\,s}

. Give your answer in metres correct to two significant figures.
