Problem 2 A mass spectrometer is constructed as shown. It is used for determining the mass of singly ionized positively charged ions (missing 1 electron). There is a uniform magnetic field B = 0.20 tesla is perpendicular to the page within the shaded region (inside the whole box). A potential difference of V = 1500 V is applied across the parallel plates L and K, which are separated by a distance d = 0.012 meter and which act as a velocity selector. (a) In which direction, relative to the coordinate system shown, should the magnetic field point in order for positive ions to move along the path shown by the dashed line in the diagram? Explain. (b) Should plate K have a positive or negative polarity, relative to plate L? Explain. (c) Calculate the magnitude of the electric filed between the plates. (d) Calculate the speed of a particle that can pass between the parallel plates without being deflected. (e) Calculate the mass of the singly charged ion that travels in a semicircle or radius R = 0.50 meter.
