Motion of Charged Particles

• What happens to a charged particle in an electric field?

  It experiences a force causing movement
• How does a charged particle move if it remains stationary in a uniform electric field?

  It moves parallel to the electric field lines
• What trajectory does a charged particle follow when in motion through a uniform electric field?

  It travels in a parabolic trajectory

  
• What determines the direction of the parabolic path of charged particles?

  The charge of the particle
• Where does a positive charge get deflected in an electric field?

  Towards the negative plate
• Where does a negative charge get deflected in an electric field?

  Towards the positive plate
• What is the force on a charged particle in an electric field?

  It is constant at all points
• What type of particle experiences no force in an electric field?

  An uncharged particle, like a neutron
• How does mass affect the deflection of a charged particle in an electric field?

  Greater mass results in smaller deflection
• How does charge affect the deflection of a charged particle in an electric field?

  Greater charge results in greater deflection
• How does speed affect the deflection of a charged particle in an electric field?

  Greater speed results in smaller deflection
• What is the relationship between electric force and charge?

  • Electric force \( F \) is proportional to charge \( Q \)
  • Formula: \( F = EQ \)
• How does the charge of a boron nucleus compare to a proton?

  Boron has 5 times the charge of a proton
• How does the mass of a boron nucleus compare to a proton?

  Boron has 11 times the mass of a proton
• What will happen to the deflection of a boron nucleus compared to a proton in an electric field?

  Boron will be less deflected than proton
• What factors affect the deflection of charged particles in an electric field?

  • Mass: Greater mass = smaller deflection
  • Charge: Greater charge = greater deflection
  • Speed: Greater speed = smaller deflection
• What is the atomic number of boron?

  5
• What is the mass number of boron?

  11
• How does a heavier particle behave in an electric field compared to a lighter particle?

  It hits the plate later with smaller curve
• What is the effect of higher mass on the trajectory of a charged particle?

  It results in less deflection
• Why does a heavier particle have a smaller curve in its path?

  It is harder to steer towards the plate
