Options:
  • A the radius of path of a charged particle moving in a uniform magnetic field is proportional to the momentum of the particle
  • B an electron beam is moving towards east, on which a perpendicular magnetic field is acting upwards. The beam will be deflected towards the north direction
  • C a positive charge is going straight away from the observer. The magnetic line of force produced due to it are in clockwise direction.
  • D while passing through a given place, the path of electron remains straight line. It can be definitely said that the magnetic field is not present at that place

The correct answer is: while passing through a given place, the path of electron remains straight line. It can be definitely said that the magnetic field is not present at that place
If the path of electron remains straight line then either magnetic field is not present at that place or velocity of electron is parallel to the magnetic field.
