In hydrogen atom, electron excites from ground state to higher energy state and its orbital velocity is reduced to 
of its initial value. The radius of the orbit in the ground state is 
. The radius of the orbit in that higher energy state is ...

Text Solution
Verified by ExpertsThe correct answer is:
D
As per question,
where subscripts 
and 
denotes higher energy state and ground state.
Orbital velocity of electron in the 
orbit is
For ground state, 
Equating (i) and (ii), we get 
Radius of 
orbit is
