  • Question 1/10
    4 / -1
    An electrically charged particle enters into a uniform magnetic induction field in a direction perpendicular to the field with a velocity v. Then, it travels
    Solutions

  • Question 2/10
    4 / -1
    A beam of protons is moving horizontally towards you. As it approaches you, it passes through a magnetic field which is directed upwards. As you see it, the magnetic field will deflect the beam to the
    Solutions

  • Question 3/10
    4 / -1
    An α-particle and a proton moving with the same kinetic energy enter a region of uniform magnetic field at right angles to the field. The ratio of the radii of the paths of a-particle to that of the proton is
    Solutions

  • Question 4/10
    4 / -1
