Consider an instrument similar to a mass spectrometer. 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:
a.The value of the potential difference through which the atom was accelerated.
b.The mass of the atom
c.The time it took the atom to move along the semi-circular part of its path in the instrument.
d.The direction of the electric field inside the velocity selector.(indicate it on the diagram.
e.The direction of the magnetic field, BI.(indicate on the diagram)
f.The chemical element of which the atom is an example.
