Problem 14
A beam of singly charged particles of 7Li moves through a uniform magnetic field at a speed of 4.0 km/s. A 7Li particle has a mass of 1.16 × 10-26 kg. The magnetic field deflects the particles' beam, and the beam leaves the magnetic field region perpendicular to the initial direction of incidence. Determine the strength of the magnetic field if the distance traveled by the 7Li beam is 3.24 cm.
