A) its kinetic and potential energies decrease.
B) potential energy increases and kinetic energy decreases
C) potential energy decreases and kinetic energy increases
D) its kinetic and potential energies increase
Correct Answer: B
Solution :
The kinetic energy of hydrogen atom in state orbits \[K=\frac{m{{Z}^{2}}{{e}^{2}}}{8\varepsilon _{0}^{2}{{h}^{2}}}\left( \frac{1}{{{n}^{2}}} \right)\] Potential energy, \[U=-\frac{m{{Z}^{2}}{{e}^{4}}}{4\varepsilon _{0}^{2}{{h}^{2}}}\left( \frac{1}{{{n}^{2}}} \right)\] Therefore when the hydrogen atom jumps from ground state to the higher energy states, then the kinetic energy decreases and the potential energy increases.
