A particle of charge ‘q’ and mass m’ enters normally (at point P) in a region of magnetic field with speed v. It comes out normally from Q after time T as shown in figure. The magnetic field B is present only in the region of radius R and is constant and uniform. Initial and final velocities are along radial direction and they are perpendicular to each other. For this to happen, which of the following expression(s) is/are correct :
  • a)
  • b)
  • c)
  • d)
    None of these
Correct answer is option 'A,B,C'. Can you explain this answer?
