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

Options

  1. Ain a straight line without acceleration
  2. Bwith force in the direction of the field
  3. Cin a circular path with a radius directly proportional to v^2
  4. Din a circular path with a radius directly proportional to its velocity

Correct answer

D. in a circular path with a radius directly proportional to its velocity

Step-by-step solution

By motion of charged particles in uniform magnetic field r= m v q B So, r v It travels in a circular path with a radius directly proportional to its velocity.
