Find the value of the magnetic field necessary to cause a proton moving at a speed of 2.50 10^3 m/s to go into a circular orbit of 15.5-cm radius.

An electron has an energy of 100 eV as it enters a magnetic field of 3.50 10−2 T. Find the radius of the orbit.

A velocity selector has a magnetic field of 0.300 T. If a perpendicular electric field of 10,000 V/m is applied, what will be the speed of the particles that will pass through the selector?
