A particle with a mass of 1.8 g and a charge of .01 μC has a velocity 20000*j m/s at time t. What is its acceleration (magnitude and direction) at that instant if it is in a uniform magnetic field B = ( i + 2j ) T? a) 0.11 m/s2 along negative z. b) 0.11 m/s2 along positive z. c) 0.11 m/s2 along positive x

A beam of electrons is simultaneously influenced by an homogeneous electric field of 15600 V/m and by a homogeneous magnetic field of 4.62 x 10-3 T. Assume that both fields are perpendicular to the electron beam and to each other. Both fields have to be oriented such that they produce no deflection of the electron beam. a) Draw the relative orientations of the vectors v, E, and B and also the forces of FE and FB .b) Determine the speed of the electrons such that there is no deflection of the electron beam. c) When the electric field is switched off, what is the radius and the period of the electron orbit?

An electron experiences an acceleration of 4.7 x 1011 m/s2 as it moves at right angles to a 7.9 mT magnetic field. How fast is the electron moving? Give your answer in m/s.

An electron moves in a circular path perpendicular to a uniform magnetic field with a magnitude of 2.03 mT. If the speed of the electron is 1.49 x 107 m/s, determine the following. (a) the radius of the circular path cm (b) the time interval required to complete one revolution Additional Materials M eBook
