A light beam travelling in the X-direction is described by the electric field Ey=(300 V/m)sin ω(t−x/c). An electron is constrained to move along the Y-direction with a speed of 2.0×10⁷ m/s. Find the maximum electric force and the maximum magnetic force on the electron respectively.

B 9.6×10⁻¹⁷ N,6.4×10⁻¹⁸ N
C 2.4×10⁻¹⁷ N,1.6×10⁻¹⁸ N
D 3.6×10⁻¹⁷ N,2.5×10⁻¹⁸ N
