A mass spectrometer is a device that selects a Particle of manual mass. An ion with electric charge q>0 starts at rest from a source S and is accelerated through a hole into a region of the constant magnetic field \vec{B} perpendicular to the Plane of the paper as shown in fig. The Particle is deflected by the magnetic field and emerges through the bottom hole at a distance d from the top hole. The mass of the particle is
