Question

A charged particle is subjected to acceleration in a cyclotron which consists of two dees ‘D₁’ and ‘D₂’. The charged particle undergoes increase in its speed.

Options

• inside D₁, D₂ and the gap between dees.

• only inside D₁.

• only in the gap between D₁ and D₂.

• only inside D₂.

Answer 1

Only in the gap between D₁ and D₂.

Explanation:

Inside the dees, there is only a magnetic field, which changes the direction of motion but does not increase speed. The particle gains energy only in the gap between the dees, where an alternating electric field accelerates it.
