Before entering a mass spectrometer, a beam of singly charged ions are filtered by a velocity selector with crossed electric and magnetic fields of E=69 V/m and B=95 mT, respectively, such that v, E and B are mutually perpendicular to one another. The ions entering the slit are forced to move in a semi-circular path due to the presence of a uniform magnetic field Bo=40 T perpendicular to the plane of the ion trajectory, and produce a spot a distance D=50 cm from the entrance slit, on a sensitive plate. Calculate the mass (in au, atomic unit) of an ion in the beam. Electronic charge -19 e=1.6x10 C, 1 au=1.67x1027 kg.

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
