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?Select one of the options below as your answer:
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°)
