If r is the radius of first orbit, the radius of nth orbit of the H atom will be:

If r is radius of first orbit , the radius of nth orbit of the H atom will be

If r is radius of first orbit , the radius of nth orbit of the H atom will be

If gt is radius of first orbit , the radius of nth orbit of the H atom will be

If the radius of first Bohr's orbit is r, then radius of second orbit will be

The expression for Bohr radius of nth orbit of an atoms is

The radius of Bohrs first orbit is r , then the radius of the first orbit in the singly ionised helium atom is

The radius or second stationary orbit in Bohr's atom is R. The radius of the third orbit in the same atom will be
