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 see problem 19 6 in book a 3 points 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 V 1 500 V d 0 012 m Region of Magnetic Field B X Positive z out of page b 3 points Should plate K have a positive or negative polarity relative to plate L Explain c 6 points Calculate the magnitude of the electric filed between the plates d 7 points Calculate the speed of a particle that can pass between the parallel plates without being deflected e 6 points Calculate the mass of the singly charged ion that travels in a semicircle of radius R 0 50 meter
