1. Assume the magnitude of the charge of particle is 100 mC, its mass is 0.03 g and its velocity is 2000 m/s. What is the magnetic force on particle? - answer is in Newtons
2. What is the acceleration of the particle?
3. What is its radius of curvature of particle in the magnetic field?
4. What should be the magnitude of this electric field? answer units in N/C
