When beryllium-7 ions (m = 11.65 x 10-27 kg)pass through a mass spectrometer, a uniform magnetic field of 0.322T curves their path directly to the center of the detector, as inthe drawing. For the same accelerating potential difference, what magnetic field should be used to send beryllium-10 ions (m= 16.63 x 10-27 kg) to the same location in the detector? Both types of ions are singly ionized (q =+e).
