Question

A proton moving in a magnetic field experiences a magnetic force of 17 N at 26o at one instant in time. At the same instant in time, an electron moving with the same speed experiences the same magnetic field. Compare the magnetic force experienced by the electron to that of the proton.

Answer 1

Force depends upon charge. They have equal and opposite charges
q = +e and -e. The magnetic forces (q v X B) will be equal and opposite also.
