A diagram of a device called a velocity selector, in which particles of a specific velocity pass through undeflected while those with greater or lesser X X X X Z velocities are deflected either upwards or downwards. An electric field is directed perpendicular to a magnetic field, producing an electric force and a magnetic force on the charged particle that can be equal in magnitude and opposite in direction and cancel. Show that particles with a speed of v-E/B will pass through the velocity selector undeflected. 10. A particle with unknown mass and charge moves with constant speed v =it passes un-deflected through a pair of parallel plates, as shown above. The plates are separated by a distance d, and a constant potential difference V is maintained between them. A uniform magnetic field of magnitude B T directed into the page exists both between the plates and in a region to the right of them as shown. After the particle passes into the region to the right of the plates where d = 6.0 x 10 3m only the magnetic field exists, its trajectory is circular with U = 1.9 x 10* m/s B - 0.20 T radius r = 0.10 m. = 0.10 m a.
