In Bohr's atomic model of hydrogen, let $K$, $P$ and $E$ be the kinetic energy, potential energy and total energy of the electron respectively. Choose the correct option when the electron undergoes transition to a higher level:
Answer: (B) $K$ decreases, $P$ and $E$ increase.
For the $n$th orbit $K = \dfrac{13.6}{n^2}\ \text{eV}$, $P = -2K$ and $E = -K$.
As $n$ increases, $K$ decreases, while $P$ and $E$ (both negative) become less negative, i.e. they increase.
