Give the magnitude and direction of the electric Lorentz force acting on a particle of charge, Q in an electric field, E. What is the consequence of the force on the charged particle?
Give the magnitude of the magnetic Lorentz force acting on a particle of charge, Q which moves at a speed v in a magnetic field, B. What rule should be applied to obtain the direction of the force? What is the consequence of this force on the charged particle?
