In a hydrogen atom, if the electron is replaced by a particle which is 200 times heavier but has the same charge, how would its radius change?

In a Bohr atom the electron is replaced by a particle of mass 150 times the mass of the electron and the same charge . If a_(0) is the radius of the first Bohr orbit of the orbital atom, then that of the new atom will be

In a Bohr atom the electron is replaced by a particle of mass 150 times the mass of the electron and the same charge. If a_(0) is the radius of the first Bohr's orbit of the orbital atom, then that of the new will be .

Define ionization energy. How would the ionization energy change when electron in hydrogen atom is replaced by a particle 200 times heavier than electron, but having the same charge?

Define ionization energy. How would the ionization energy change when electron in hydrogen atom is replaced by a particle 200 times heavier than electron, but having the same charge?

If electron of hydrogen atom is replaced by another particle of same charge but of double mass then:
