Electrostatics Question 608
Question: A proton moving with a constant velocity passes through a region of space without any change in its velocity. If E and B represent the electric and magnetic fields respectively, Identify which of the following options can be true for the space.
Options:
A) $ E≠0,B=0 $
B) $ E=0,B≠0 $
C) $ E=0,B=0 $
D) $ E≠0,B≠0 $
Show Answer
Answer:
Correct Answer: C
Solution:
A proton moving through a space contain electric and magnetic field will experience a force
$F=q(\rightarrow E+\rightarrow v\times\rightarrow B)$
If the proton passes through the space without changing its velocity then two cases can be possible:
i) either E=0 and B=0. (Trivial case)
ii) or, E≠0 and B≠0 (motion of the proton (v) is perpendicular to the B)
