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 7.13 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.5100 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle.

Answer:

d = 0.030 m

Explanation:

The radius of curvature (r) of the two isotopes can be calculated using the following equation:

[tex] r = \frac{m*v}{q*B} [/tex]

Where:

  • m: is the mass of the isotope, m₁ (C-12) = 1.993x10⁻²⁶ kg, m₂(C-13) = 2.159x10⁻²⁶ kg  
  • v: is the speed of the isotpe, v₁ (C-12) = v₂ (C-13) = 7.13x10⁵ m/s  
  • B: is the magnetic field = 0.5100 T
  • q: is the charge of the isotopes, q₁ = q₂ = +1.6x10⁻¹⁹ C

The radius of the isotope carbon-12 is:

[tex] r_{1} = \frac{1.993 \cdto 10^{-26} kg*7.13 \cdot 10^{5} m/s}{1.6 \cdot 10^{-19} C*0.5100 T} = 0.174 m [/tex]

Simimlarly, the radius of the isotope carbon-13 is:

[tex] r_{2} = \frac{2.159 \cdto 10^{-26} kg*7.13 \cdot 10^{5} m/s}{1.6 \cdot 10^{-19} C*0.5100 T} = 0.189 m [/tex]  

Finally, the spatial separation between the two isotopes after they have traveled through a half-circle ([tex]d_{T}[/tex]) is:

[tex] d_{T} = d_{2} - d_{1} = 2r_{2} - 2r_{1} = 2 (0.189 m - 0.174 m) = 0.030 m [/tex]

I hope it helps you!    

The spatial separation between the two isotopes after they have traveled through a half-circle should be 0.030m.

Calculation of the spatial separation:

Since

r = m*v/q * B

here,

m is the mass of the isotope,

m₁ (C-12) = 1.993x10⁻²⁶ kg,

m₂(C-13) = 2.159x10⁻²⁶ kg  

v is the speed of the isotpe,

v₁ (C-12)

v₂ (C-13) = 7.13x10⁵ m/s  

B is the magnetic field = 0.5100 T

q is the charge of the isotopes, q₁ = q₂ = +1.6x10⁻¹⁹ C

Now the radius for carbon 12 is

= 1.99310*^-26 * 7.13*10^15/1.6*10^19 * 0.5100 T

= 0.174m

And, the radius for carbon 13 is

= 2.15910^-26 * 7.13.10^5/1.6*10^-19*0.5100T

= 0.189m

So, here the spatial separation should be

= d_2-d_1

= 2r_2 - 2r_1

= 2(0.189m - 0.174m)

= 0.030m
