A hydrogen atom has an electron moving in a circular orbit of radius

5.29\times10^{-11}\,\text{m}

around its nucleus. Calculate the speed of the electron in this orbit. (Use

k=8.99\times10^{9}\,\text{N}\,\text{m}^2\,\text{C}^{-2}

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

, and

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