Question

1. An electron is accelerated from rest by a potential difference of 310 V. It then enters a uniform magnetic field of magnitude 260 mT with its velocity perpendicular to the field. Calculate the radius of its path in the magnetic field. 2. An electron in a TV camera tube is moving at 9.00×106 m/s in a magnetic field of strength 79 mT. Without knowing the direction of the field, what can you say about the greatest and least magnitude of the force acting on the electron due to the field? Maximum force? Minimum force? 3. An electron has an initial velocity of (10.5j + 13.0k) km/s and a constant acceleration of (1.30×1012 m/s2)i in a region in which uniform electric and magnetic fields are present. If B =(400μT)i, find the electric field E. Ex? Ey? Ez?
