Two isotopes of carbon, carbon-12 and carbon-13, have masses of 1.993 10-26 kg and 2.159 10-26 kg, respectively. These two isotopes are singly ionized ( e) and each is given a speed of 6.50 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.5700 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle.

d=0.024m

Explanation:

The mass of the isotopes are

The velocity of isotopes are

Charge q=+e=1.6×10⁻¹⁹C and the magnetic field is B=0.5700T

The radius of circular paths for isotopes are:

So the spatial separation between two isotopes given as:

d=2r₂-2r₁

d=2(0.154)-2(0.142)  

d=0.024m

heat the gas and measure the pressure

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
