In a mass spectrograph, an ion is accelerated through a potential difference of 1 kV between points S and point P. Then the ion enters a circular section with a uniform magnetic field of 0.5 T at an angle of 60° and is captured by a photographic plate (see figure). The distance between points P and C is 1 m. Use pi = 3.14 . A. If the electric charge of the ion is q and the mass of the ion is m, then the value of the ratio of q/m is....x10³ C/kg. B.
