If the speed of electron in the first bohr orbit of hydrogen atom is x then the speed of the electron in the third Bohr orbit of hydrogen is

Compare the speed of electron in the first Bohr orbit of hydrogen atom to the speed of light.

The energy of an electron in the nth Bohr orbit of hydrogen atom is

If the speed of electron in the Bohr's first orbit of hydrogen atom be x, then the speed of electron in second orbit of He^(+1) is

If the velocity of an electron in the Bohr first orbit of hydrogen atom is x, then find the velocity of the electron in the third Bohr's orbit.

If the speed of electron in first Bohr orbit of hydrogen be 'x' then speed of the electron in second orbit of He^(+) is

The kinetic energy of electron in the first Bohr orbit of the hydrogen atom is

The angular speed of the electron in the first orbit in a hydrogen atom is

Show that the speed of electron in the second orbit of He^(+) atom is equal to the speed of electron in the first orbit of hydrogen atom.
