Question:
A charged particle is subjected to acceleration in a cyclotron which consists of two dees '\(D_1\)' and '\(D_2\)'. The charged particle undergoes increase in its speed.
A charged particle is subjected to acceleration in a cyclotron which consists of two dees '\(D_1\)' and '\(D_2\)'. The charged particle undergoes increase in its speed.
Show Hint
Cyclotron:
Magnetic field bends, electric field accelerates

- inside \(D_1, D_2\) and the gap between dees.
- only inside \(D_1\).
- only in the gap between \(D_1\) and \(D_2\).
- only inside \(D_2\).
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
• Inside dees: only magnetic field acts → no work done
• Gap between dees: electric field accelerates particle
Step 1: Inside dees.
Velocity direction changes, not magnitude.
Step 2: Between dees.
Electric field increases kinetic energy.
Step 3: Conclusion.
Speed increases only in gap. Final Answer: Option (C)
