Answer:
b. electromagnetic force
Step-by-step explanation:
Electromagnetism is in charge of describing the phenomena that develop from the intervention of electric charges, both in motion and at rest, which give rise to electric and magnetic fields. Moving electric charges generate an electric field around them, as well as a magnetic field. This magnetic field, in turn, exerts a force on all electrical charges within its scope: the electromagnetic force. For a particle subjected to an electric field combined with a magnetic field, the total electromagnetic force or Lorentz force on that particle is given by:
[tex]F=qE+qv\times B[/tex]
Where:
[tex]v=Speed\hspace{3}of\hspace{3}the\hspace{3}charge\\E=Electric\hspace{3} field\hspace{3} strength\\B=Magnetic\hspace{3} field\hspace{3} strength[/tex]
