Atoms And Nuclei Question 35
Question: When a hydrogen atom is raised from the ground state to an excited state [CBSE PMT 1995; AMU (Med.) 1999]
Options:
A) P.E. increases and K.E. decreases
B) P.E. decreases and K.E. increases
C) Both kinetic energy and potential energy increase
D) Both K.E. and P.E. decrease
Show Answer
Answer:
Correct Answer: A
Solution:
P.E. $ \propto -\frac{1}{r} $ and K.E. $ \propto \frac{1}{r} $ As r increases so K.E. decreases but P.E. increases.
