I need help with this question, I don't fully understand it and there is also a part 2 which asks to "find the magnitude of the force F (in kg•m/s^2) necessary to make the block move."​

Based on details in the riddle of the rosetta stone, which statement best describes jean-baptiste fourier’s influence on jean-françois champollion?

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
