If the speed of the electron in the first Bohr orbit of hydrogen atom be '

x

' then the speed of electron in the third Bohr orbit is

View answer and explanation

Correct option: B

\frac{x}{3}

Option B (

\frac{x}{3}

) is correct because the speed of an electron in a Bohr orbit is inversely proportional to the principal quantum number (n).
