If a charged particle of charge to mass ratio q/m = α is entering in a uniform magnetic field of strength B which is extended up to 4d as shown in figure at a speed v = 2αdB,  then which of the following is incorrect
  • a)
    the time for which particle will be in the magnetic field is 2π/αβ
  • b)
    the charge will move on a circular path and will come out from magnetic field at a distance 4d from the point of insertion. 
  • c)
    angle subtended by charged particle at the centre of circular path is 2π
  • d)
    the charged particle will subtended an angle of 90° at the centre of circular path
Correct answer is option 'A,C,D'. Can you explain this answer?
Verified Answer
If a charged particle of charge to mass ratio q/m =αis entering ...
Electromagnetic force will provide the necessary centripetal force.

⇒ 
 
i.e. the electron will move out after traveling on a semicircular path of radius r = 2d.
The correct answers are: angle subtended by charged particle at the centre of circular path is  2π, the time for which particle will be in the magnetic field is the charged particle will subtended an angle of 90° at the centre of circular path
