Suppose that a region with a uniform magnetic field B also has a uniform electric field E perpendicular to the magnetic field, an arrangement called crossed fields. Show that for a charged particle moving in such crossed fields in a direction perpendicular to both E and B, the electric force cancels the magnetic force, provided the particle has a speed v= E/B If the magnetic field is in the vertical upward direction and the electric field is in the northward...

A beam of electrons is accelerated through a potential difference of 10 kV before entering a region having uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the direction in which the electron is moving. If the magnetic field in this region has a value of 0.010 T, what magnitude of the electric field is required if the particles are to be undeflected as they pass through the region?
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...

A beam of protons is directed in a straight line along the positive ?‑direction through a region of space in which there are crossed electric and magnetic fields. If the electric field magnitude is ?=410 V/m in the negative ?‑direction and the protons move at a constant speed of ?=1.5×105 m/s, what must the direction and magnitude of the magnetic field be in order for the beam of protons to continue undeflected along its straight-line trajectory? magnitude of the magnetic...

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...

A charged particle moves through a region of space that has both a uniform electric field and a uniform magnetic field. What is the condition for these fields in order for the particle to move through this region at a constant velocity? Does the answer depend on the sign of the particle’s electric charge?
