Dual Nature Of Light Question 38
When the speed of electrons increases, then the value of its charge to mass ratio [MP PMT 1994]
Options:
A) Increases in temperature
B) Decreases.
C) Remains unchanged
D) Increases to some velocity and then begins to decrease
Show Answer
Answer:
Correct Answer: B
Solution:
Refer Q.No. 9. Here the velocity of electron increases, so as per Einstein?s equation mass of the electron increases, hence the specific charge $ \frac{e}{m} $ decreases.
