An electron is sent through a mass spectrometer similar to the diagram shown below. The electron starts from rest and is accelerated East by an electric potential difference of 120 V. It then passes into a uniform magnetic field of magnitude 0.12T [North]. The electron follows a curve path, changing direction by 180° before it strikes a sensor. What is the displacement of the electron from the time it enters the magnetic field to the time it has changed direction by 180°?
