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 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. Source 10. A particle with unknown mass and charge moves with constant speed vit 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 BT directed into the page exists both between the plates s and I in a region to the right of them as shown. After the particle passes into the region to the right of the plates where only the magnetic field exists, its trajectory is circular with radius r= 0.10 m. a.
