Question

An electron accelerated from rest through a voltage of 320 V enters a region of constant magnetic field. If the electron follows a circular path with a radius of 28 cm, what is the magnitude of the magnetic field?
______mT

A particle with a charge of 14 C experiences a force of 2.7 x 10-4 N when it moves at right angles to a magnetic field with a speed of 28.2 m/s. What force does this particle experience when it moves with a speed of 5.7 m/s at an angle of 24.5relative to the magnetic field? _______N An electron accelerated from rest through a voltage of 320 V enters a region of constant magnetic field.
