mixture contains two types of particles, "K and an unknown substance, X. "K has a mass of 6.64x10-20 kg but the mass of substance X is not known. The charge on both ubstances is the same but also unknown. The particles are launched into the mass spectrometer at a speed of 6750 m/s . The mass spectrometer has a 7.47x10" T magnetic field pointing out of the page (as shown below). The K particles hit a semi-circular detector with a diameter of 25.0 cm and substance X hits the detector with a liameter of 28.0 cm .
