Picture an instrument similar to a mass spectrometer. In which picture, a singly-ionized atom is accelerated from rest through a potential difference, DV, until it passes through the slit, S1. The atom then enters a velocity selector in which the strength of the magnetic field, BSEL, = 4T and is directed into the plane of the paper .
The electric field strength in the selector is 4.819 x 105 N/C. The atom passes straight through the selector without any deflection of its path. It then enters the main instrument in which the strength of the magnetic field, BI, = 2 T and follows a semi-circular path whose diameter is 0.02 m.
From the information above, determine the magnitude of the magnetic field, BI.
Communication satellites are placed in geosynchronous orbit, i.e., in circular orbit such that they complete one full revolution about the earth in one sidereal day.
