Q127 / 180 · COMEDK 2015 · Physics

A charged particle moves in a uniform magnetic field. The velocity of the particle at some instant makes an acute angle with the magnetic field. The path of the particle will be

  • A
    a straight line
  • B
    a circle
  • Correct answer
    C
    a helix with uniform piteh
  • D
    a helix with non-uniform pitch

Solution

When a charged particle moves in uniform magnetic field making an acute angle with the direction of magnetic field, then it moves on helical path with uniform pitch.

Hence, the correct answer is option: 'C'.
