The gure below shows the schematic for a mass spectrometer which consists of a velocity selector and a deflection chamber. The magnitude of the magnetic field in both the velocity selector and the deflection chamber is 0.0110 T, and the electric eld between the plates of the velocity selector is 2600 V/m. If a singly charged ion with a mass of 6.70 x 10'27 kg travels through the velocity selector and into the deflection chamber, determine the radius of its trajectory in the deflection chamber. :m '7
