Atomic Structure Question 408
Question: An electron in an atom jumps in such a way that its kinetic energy changes from x to $ \frac{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 $ P.E.=-\frac{2x}{4}+( 2x )=\frac{3}{2}x $
