Problem

An electron (q=−1.6×10−19 Cq = -1.6\times10^{-19}\,\text{C}) moves with speed 1.0×106 m s−11.0\times10^{6}\,\text{m s}^{-1} along the positive yy-axis through simultaneous uniform fields: an electric field 200 V m−1200\,\text{V m}^{-1} along the positive xx-axis and a magnetic field 0.50 T0.50\,\text{T} along the positive zz-axis. What is the magnitude of the net force on the electron at this instant? a) 5.00×10−14 N5.00 \times 10^{-14}\,\text{N} b) 7.68×10−14 N7.68 \times 10^{-14}\,\text{N} c) 8.03×10−14 N8.03 \times 10^{-14}\,\text{N} d) 1.60×10−13 N1.60 \times 10^{-13}\,\text{N}
