  • Question 1/10
    4 / -1
    If a proton, deutron and α–particle on being accelerated by the same potential difference enters perpendicular to the magnetic field, then the ratio of their kinetic energies is
    Solutions

  • Question 2/10
    4 / -1
    A proton (or charged particle) moving with velocity v is acted upon by electric field E and magnetic field B. The proton will move undeflected if
    Solutions

  • Question 3/10
    4 / -1
    An electron is moving on a circular path of radius r with speed v in a transverse magnetic field B. e/m for it will be
    Solutions

  • Question 4/10
    4 / -1
    An electron enters a magnetic field whose direction is perpendicular to the velocity of the electron. Then
  • Question 5/10
    4 / -1
    A charge moving with velocity v in X-direction is subjected to a field of magnetic induction in the negative X-direction. As a result, the charge will
    Solutions

  • Question 6/10
    4 / -1
    A particle moving in a magnetic field increases its velocity, then its radius of the circle
    Solutions

  • Question 7/10
    4 / -1
    A particle is moving in a uniform magnetic field, then
  • Question 8/10
    4 / -1

    Solutions

  • Question 9/10
    4 / -1
    A proton moving with a velocity 2.5 × 107 m/s, enters a magnetic field of intensity 2.5 T making an angle 30° with the magnetic field. The force on the proton is
    Solutions

  • Question 10/10
    4 / -1
    A beam of electrons passes undeflected through mutually perpendicular electric and magnetic fields. If the electric field is switched off and the same magnetic field is maintained, the electrons move
