Question

The orbital speed of the electron in the ground state of hydrogen is v. What will be its orbital speed when it is excited to the energy state –3.4eV. 

Solution

Correct option is

Energy state –3.4 eV corresponds to a level n given by  which gives n = 2. 

Now, orbital speed .

Hence the orbital speed in the excited state is .
