Question:medium

A charged particle moves through a magnetic field perpendicular to its direction. Then

Show Hint

Magnetic force can change the direction of velocity but never its magnitude. Hence: K.E. = constant, Momentum (vector) = changing

  • kinetic energy changes but the momentum is constant
  • the momentum changes but the kinetic energy is constant
  • both momentum and kinetic energy of the particle are not constant
  • both momentum and kinetic energy of the particle are constant
