A charged particle is injected at 261 m/s into a 0.0719-T uniform magnetic magnetic field perpendicularly to the field. What is the charge-to-mass ratio of this particle
When a charged particle moves at an angle of 11° with respect to a magnetic field, it experiences a magnetic force of magnitude F. At what angle(less than 90°) by respect to this field will this particle, moving at the similar speed, experience a mag..
