Crossed E and B Fields. A particle with initial velocity V = (5.85 * 10^3 m/s) j enters a region of uniform electric and magnetic fields. The magnetic field in the region is B= -(1.350 T) k . Calculate the magnitude and direction of the electric field in the region if the particle is to pass through undeflected, for a particle of charge (a) +0.640 nC and (b) -0.320 nC. You can ignore the weight of the particle.

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...

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...

An antiproton is a particle with the same mass as a proton, but charge of an electron. An antiproton traveling with a speed of 2.0 × 107 m/s in the −y direction enters a region of uniform magnetic and electric fields. The magnetic field has magnitude 0.5 T oriented along the +x direction. What is the magnitude and direction of an electric field required for the antiproton to maintain a constant speed and direction?

A particle with a mass of 6.4 × 10–27 kg and a charge of +3.20 × 10–19 C is accelerated from rest through a potential difference of 9.0 × 106 V. The particle then enters a uniform 0.82-T magnetic field. If the particle’s velocity is perpendicular to the magnetic field at all times, what is the magnitude of the magnetic force exerted on the particle?
