An electron is accelerated by a set of parallel plates as shown below. A} Determine the magnitude and direction of the electric eld between the plates [2] B} Determine the speed of the electron as it exits the right hand plate. [2] +0050 111+ - _. 9 0V C) The electron now enters a uniform magnetic eld with the velocity in (B). The diagram below shows the direction of motion. The magnitude of the magnetic field is 8.5 T. HP _ P veIOCIty i) State the direction of the magnetic eld. [1] ii} Determine the period of the motion of the electron. [2] iii) Explain why the electron moves {1} At a constant speed. [1] (2} On a circular path. [2] +300 V
