A x B ta L C Beginning at time t = 0 an electron accelerates very briefly in the direction having an angle with the z-axis, as shown in the diagram. The magnitude of this acceleration is a. Detectors of electric and magnetic fields are placed at locations A, B, and C, all a distance d from the charge. What can we say about the radiative MAGNETIC field at location A? The radiative magnetic field points in the opposite direction from the radiative electric field. The radiative magnetic field points into the page The radiative magnetic field points out of the page What is the magnitude of the radiative magnatic field at location A? Use k for Coulomb's constant, c for speed of light, e for electric charge, and directly type "theta" for angle in your answer. B=
