An electron makes a transition from an excited state to the ground state of a hydrogen like atom. Out of the following statements which one is correct?

Options:

Answer:

Solution:

$Potential energy = - \frac{1}{4 π ε _{0}} \cdot \frac{ze ^{2}}{r} Kinetic energy = - \frac{1}{2} (P.E.) = \frac{1}{8 π ε _{0}} \cdot \frac{ze ^{2}}{r} Total energy \frac{1}{2} (P.E.) = - \frac{1}{8 π ε _{0}} \frac{ze ^{2}}{r}$ As $r$ decreases K.E, increases but P.E. and T.E. decreases (since they are negative).
