Magnetic Effects Of Current Question 12
Question: Assertion : An electron and proton enters a magnetic field with equal velocities, then, the force experienced by the proton will be more than electron. Reason : The mass of proton is 1837 times more than electron.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.

Answer:
Correct Answer: E
Solution:
The force experienced by a charge particle in a magnetic field is given by, $ \overrightarrow{F}=q(\overrightarrow{v}\times \overrightarrow{B}) $ which is independent of mass. As q, v and B are same for both the electron and proton, hence both will experience same force.
