Magnetic field, B = 0.552 T
Accelerating voltage, V = 2567 V
Path radius of the charged particles in the magnetic field region in a mass spectrometer set up is given by,
r = (1/B )*sqrt(2mV / q)
where m is the mass of the particle and q is the charge on it.
Path radius of Ca+ ion.
Mass of the Ca+ ion is, m = 40.1 amu = 40.1 x 1.661 x 10^-27 kg
m = 66.6061 x 10^-27 kg
Charge on the Ca+ ion is, q = +1e = 1.6 x 10^-19 C
Path radius r is,
r = (1 / B )*sqrt(2mV / q)
r = (1/0.552)* sqrt[(2 x 66.6061 x 10^-27 x 2567) / 1.6 x 10^-19 ]
r = 8.375 cm
