Select the correct answer. 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°).
