1.
The Kinetic energy of the electron in an orbit of radius 
in hydrogen atom is (
electronic charge)
in hydrogen atom is (electronic charge)
2.
Imagine an atom made up of proton and a hypothetical particle of double the mass of electron, but having the same charge as that of electron. Apply the Bohr atom model and consider all possible transitions of this hypothetical particle to the first excited level. The longest wavelength photon that will be emitted has wavelength 
(given in terms of Rydberg constant 
for hydrogen atom) equal to
(given in terms of Rydberg constant for hydrogen atom) equal to
3.
If 
and 
are the potential energy and kinetic energy of the electron in stationary orbit in the hydrogen atom, the value of 
is
and are the potential energy and kinetic energy of the electron in stationary orbit in the hydrogen atom, the value of is
4.
Let the PE of hydrogen atom in the ground state be zero. Then its total energy in the first excited state will be

An alpha nucleus of energy 
bombards a heavy nuclear target of charge 
. Then the distance of closest approach for the alpha nucleus will be proportional to
