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...
The velocity selector in in a mass spectrometer has a uniform 0.0506 T magnetic field oriented in the negative y direction and a uniform 294 kV/m electric field oriented in the positive z direction. What is the kinetic energy (in electron volts) of the electron that will pass through this velocity selector in the +x direction undeflected?
The velocity selector in in a mass spectrometer has a uniform 0.0642 T magnetic field oriented in the negative y direction and a uniform 238 kV/m electric field oriented in the positive z direction. What is the kinetic energy (in electron volts) of the electron that will pass through this velocity selector in the +x direction undeflected ?

An electron moves through a region of crossed electric and magnetic fields. The electric field E = 2 000 V/m and is directed straight down. The magnetic field B = 0.80 T and is directed to the left. Specify the directions of electric and magnetic forces on the electron if it moves into the paper. For what velocity v of the electron will the electric force exactly cancel the magnetic force? A rod(length = 10 cm)...
A)What is the velocity of a beam of electrons that goes undeflected when passing through perpendicular electric and magnetic fields of magnitude 6800 v/m and 7.8×10-3T , respectively? B)What is the radius of the electron orbit if the electric field is turned off?
A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magnitude of 3.26 mT. At one instant the velocity of the proton is in the positive y direction and has a magnitude of 1980 m/s. At that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 5.92 V/m, (b)...
