A proton moving with a constant velocity passes through a region without any change in its velocity. Then in this region:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → E = 0, B = 0
If $E≠0$, the photon will experience Coloumb force and if $B≠0$, the photon will experience Lorentz force and thus in both the cases, velocity changes.
