Singly ionized (one electron removed) atoms are accelerated and then passed through a velocity selector consisting of perpendicular electric and magnetic fields. The electric field is 157 V/m and the magnetic field is 3.12×10−2 T . The ions next enter a uniform magnetic field of magnitude 1.78×10−2 T that is oriented perpendicular to their velocity. Part A How fast are the ions moving when they emerge from the velocity selector? Part B If the radius of the path of the...

The velocity selector in in a mass spectrometer consists of a uniform magnetic field oriented at 90 degrees to a uniform electric field so that a charge particle entering the region perpendicular to both fields will experience an electric force and a magnetic force that are oppositely directed. If the uniform magnetic field has a magnitude of 11.2 mT, then calculate the magnitude of the electric field that will cause a proton entering the velocity selector at 16.1 km/s to...

5) In the device diagrammed below an accelerator injects a beam of positively charged ions into the evacuated space between two metal plates. The ions are assumed to be missing one electron and they all seem to leave the accelerator with the same speed. A uniform magnetic field of magnitude 0.1 T is maintained between the plates. In separate experiments beams of ions are injected into the space between the plates . In the first experiment the beam of ions...

In a laboratory experiment, a beam of electrons is accelerated from rest through a 148-V potential difference. The beam then enters a uniform magnetic field and follows a circular path of radius r = 19.1 cm in the field region. (a) What is the angle between the magnetic field and the electrons' velocity? (b) What is the magnitude of the magnetic field? Submit Answer
Velocity Selector-multiple choice
The Velocity SelectorIn experiments where all the charged particles in a beam are required to have the same velocity (for example, when entering a mass spectrometer), scientists use a velocity selector. A velocity selector has a region of uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the motion of the charged particles. Both the electric and magnetic fields exert a force on the charged particles. If a particle has precisely the right velocity, the...
