A proton moving with a constant velocity passes through a region without any change in its velocity. Then in this region :
- A \( E = 0, B = 0 \)
- B \( E = 0, B \neq 0 \)
- C \( E \neq 0, B = 0 \)
- D \( E \neq 0, B \neq 0 \)
Answer & Solution
Correct Answer
(D) \( E \neq 0, B \neq 0 \)
Step-by-step Solution
Detailed explanation
\(\vec{F}=0\) \(\vec{F}=q(\vec{E}+\vec{v} \times \vec{B})\) \(\vec{E}+\vec{v} \times \vec{B}=0\) D) \(E \neq 0, B \neq 0\)
