The speed of electron in the innermost orbit of the hydrogen atom is? Bohar radius = 52.9pm given

Given 
r=52.9 pm
m_e=9.11*10^-31 kg

we know that,
velocity or speed of the electron in the first orbit of hydrogen is 2.18*10⁸ cm sec^-1 or 2.19*10⁸ cm sec^-1.
now for innermost orbit,velocity or speed of the electron is
s=2.19*10⁸*10^-2 m s^-1
 =2.19*10⁶ m s^-1.
