Radius of first bohr's orbit of hydrogen atom is 0.53 A then the radius of `3^(rd)` bohr orbit is :-

Radius of 3^(rd) Bohr orbit of hydrogen atom

Radius of Bohr's orbit of hydrogen atom is

Radius of Bohr's orbit of hydrogen atom is

Radius of Bohr's orbit of hydrogen atom is

The radius of first Bohr orbit of hydrogen atom is 0.53Å . Then the radius of first Bohr-orbit of mesnoic atom (negative meson has mass 207 times that of electron but same charge) is:

If the radius of 1st Bohr orbit in hydrogen atom is 0.5 A^@ 'then radius of 3rd Bohr orbit is

Radius of 3rd Bohr orbit is
