What is the magnetic force on a stationary proton in a magnetic field of 0.50 tesla? for a proton, q = 1.6 * 10-19 coulombs

If the particle is not moving relative to the field, the force is 0

The answers would be as follows:

Susan’s kinetic energy is (1,250) joules. Susan’s kinetic energy is greater than Hannah’s because (speed has a greater effect than mass). 

Hope this answers the question. Have a nice day. Feel free to ask more questions.
