One beam of electrons moves at right angles to a magnetic field. The force on these electrons is 4.9 * 10-14 newtons. A second beam travels at the same speed, but at a 30° angle with the magnetic field. What force is on these electrons?

A. (4.9 * 10-14 newtons) · tan (30°)

B. (4.9 * 10-14 newtons) · sin (30°)

C. (4.9 * 10-14 newtons) · cos (30°)

D. (4.9 * 10-14 newtons) · arctan (30°)

E. (4.9 * 10-14 newtons) · arccos (30°)
