Ascientist builds an apparatus to measure the charge to mass ratio of ions. an ion is first accelerated to a speed of 5.00 x 10 m/s. it then passes through a region of magnetic field, with a of 1.88 x 10-2 t, perpendicular to the lon's velocity. because the lon is moving so fast, it is only in the presence of the magnetic field for 2.00x 10-7s upon exiting the magnetic field, the scientist measures that the ion was defilected a distance of 3.00 cm in a direction perpendicular to its initial velocity (e) what is the ratio of the absolute value of the lon's charge to its mass (in c/kg)? assume the velocity change is small, and that the component of the velocity along the lon's original direction does not change noticeably. c/kg (b) suppose the scientist determines the ion is singly charged, that is, the magnitude of its charge is that of a proton. what is the mass of the ion (in kg)? kg
