A pulse of electromagnetic radiation is O 1. (0, 0, 3 x 105 T) propagating in the -y direction. You place a detector at location O 2. (0, 0, -3 x 105 T) (0, -5 m, 0) m 3. (0, -3 x 105 T, 0) At time t = 0, the detector detects an elec- 4. (0, -0.001 T, O) tric field of magnitude 300,000 V/m in the +x direction. At that instant, what is the 5. (0, 0, 0.001 T) magnetic field vector at the location of the detector? 6. (0, 0, -0.001 T) O 7. (0, 0.001 T, O) 8. (0, 3 x 105 T, 0)
