Atomic Structure Question 484
Question: An electron in an atom jumps in such a way that its kinetic energy changes from $ x $ to $ x/4 $ . The change in potential energy will be:
Options:
A) $ +\frac{3}{2}x $
B) $ -\frac{3}{8}x $
C) $ +\frac{3}{4}x $
D) $ -\frac{3}{4}x $
Show Answer
Answer:
Correct Answer: A
Solution:
- Change in $ PE=-\frac{2x}{4}+(2x)\Rightarrow \frac{3}{2}x $
