Answer:
they have the same mass
Explanation:
The force applied by the field is a function of the charge and velocity, so the acceleration experienced by a particle will be dependent upon its mass. Particles in orbits with the same radius are exhibiting the same acceleration, so must have the same mass.
All three choices are correct.
Well it does carry blood and oxygen! Sorry but I'm not sure about 2 and 4.
