When electrons are discharged from an electron gun, their motion can be controlled by: A additional electric fields only B additional magnetic fields only C additional electric and magnetic fields D the motion of the electrons cannot be controlled A single positively charged particle with a charge of +1.6 x 1019C travels at a velocity of 30ms at an angle of 30 to a magnetic field, B, of strength 6.0 x 10-T. What is the magnitude of the force the particle will experience from the magnetic field? A single positively charged particle with a charge of +1.6 x 10-19C travels at a velocity of 60ms at an angle of 50 to a magnetic field, B. The force on the particle is 1.5 x 10-24 N. What is the magnitude of the magnetic field acting on the charged particle?
