The radium then bombards nearby bone cells with alpha particles, causing them to "crumble." Radium poisoning investigations often center on the dentification of radium and sotopes in bone samples using a mass spectrometer. Pictured is a schematic of a sh g the p pect Simpl Calcium barium (another alkaline earth metal) and radium isotopes entering the chamber. The region shown is immersed in a AV. constant magnetic field of 0.352 T pointing out of the plane of the schematic. Motion of the positively-charged isotopes toward the right was initiated by a potential difference of 2567 V on the two plates shown.

Explanation / Answer

When ion is accelerated through Potential difference.

q deltaV = m v^2 / 2

1.6 x 10^-19 x 2567 = (40.078 x 1.66 x 10^-27) v^2 /2

v = 111117.1 m/s

when charge moves in magnetic field then magnetic force will act on ion
in perpendicular direction of velocity vector.

so ion will move in circular path.

q v B = m v^2 / r

r = m v / qB

= ((40.078 x 1.66 x 10^-27) ( 111117.1)) / (1.6 x 10^-19 x 0.352)

r = 0.131 m .....Ans
