In a mixture of $$H - He^+$$ gas ($$He^+$$ is singly ionized He atom), H atoms and $$He^+$$ ions are excited to their respective first excited states. Subsequently, H atoms transfer their total excitation energy to $$He^+$$ ions (by collisions). Assume that the Bohr model of atomis exactly valid.

The quantum number n ofthe state finally populated in $$He^+$$ ions is

The ratio of the kinetic energy of the n = 2 electron for the H atom to that of $$He^{+}$$ ion is
A small block of mass M moves on frictionless surface of an inclined plane, as shown in figure. The angle of the incline suddenly changes from $$60^\circ$$ to $$30^\circ$$ at point B.
The block is initially at rest at A. Assume that collisions between the block and the incline are totally inelastic (g = 10 m/s$$^2$$)
