B) is in the same direction in electric and magnetic fields.
C) is parallel to a magnetic field and perpendicular to an electric field.
D) is parallel to an electric field and perpendicular to a magnetic field.
E) is zero in both if the charge is not moving.

Quizplus · Accepted Answer

The force exerted on a charge in an electric field is parallel to the direction of the field, while the force due to a magnetic field is perpendicular to both the direction of the magnetic field and the velocity of the moving charge, as described by the right-hand rule. This distinction is a fundamental principle of electromagnetism.
