A charged particle is moving in a circular orbit with radius r and orbital angular frequency in the presence of a magnetic field. The orbit is enclosed within a larger circular metallic frame. The frame is concentric and coplanar with the orbit. The radius of the frame is now gradually decreased. Assuming that the particle remains within the frame at all times, what changes to the trajectory of the particle will occu

Options

  1. AThe radius of the orbit will gradually decrease and the frequency will gradually increase.
  2. BThe radius of the orbit will gradually increase and the frequency will gradually decrease.
  3. CThe radius of the orbit will remain the same but the frequency will gradually increase.
  4. DBoth the radius of the orbit and the frequency will remain unchanged.

Correct answer

A. The radius of the orbit will gradually decrease and the frequency will gradually increase.
