Which of the following statements correctly describes how the sign of a charge affects the direction of the magnetic force it experiences in a uniform magnetic field?
(a) Reversing the sign of the charge leaves the direction of the magnetic force unchanged; only its magnitude is affected.
(b) Positive and negative charges moving with the same velocity in the same uniform magnetic field experience forces in the same direction.
(c) The magnetic force on a negative charge points in the exact opposite direction to that on an otherwise identical positive charge.
(d) A positive charge is pushed parallel to the magnetic field, whereas a negative charge is pushed antiparallel to the field.
